Blood donation and transfusion

Become a blood donor. That's the gist of it. I'll tell you a bit about that. I've been trying to write this post for a very long time now. I've been to the donor clinic about four times already in the past two years. It was always something preventing me from donating. Either me not being originally from this country, having to give samples first, or having to wait because I had been traveling, or having to get some medical documentation they needed to verify first. Right now, after my first proper donation, things are finally falling into place. Vesna and I were persistent, if nothing.

Donating blood is not something that was strongly encouraged in our lives. I know that some high-schools did it. I don't think my class did. It was a chance for students to skip a school-day. If you're employed, depending on the country you are located in and your employer, you might get a paid day off, or there might be other incentives. Not in Ireland, though, but it's not something I was looking for. I'm donating because it's the right thing to do and that should be a proper motivation for others as well.

There are people who oppose it out of an overall hidden fear that doing it might lead to complications, that the procedure can cause an infection in the donor's organism, but that fear is largely unfounded. Every kit used for the donation is brand new and safety procedures are strictly adhered to.

While the best thing is to avoid unnecessary transfusion, we are no strangers to receiving it when the need arises. Blood transfusion is used as a support during surgeries and often for children and people over 65. According to the WHO, up to 76% of blood transfusions is for the people over 65. We might as well develop better life practices now and spread the word while we're young, because, when we get older, chances are we'll need a blood transfusion.


This goes hand in hand with the social sensitivity we should have. We might find ourselves in such a situation where blood donation could save our lives. As minuscule as that risk may be, the blood we receive must come from somewhere. In essence, we're all relying on the good will of some stranger and we can be that stranger to someone.

Carl Sagan said that we're all made of stars:

The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars.

We are inter-compatible in a way. Depending on the variables, we can share some of the body parts between us. Blood would be one of them.

The overall process of donating is easy. Nowadays, there's a questionnaire mostly comprised of questions about your past and current illnesses (if any), a quick check for iron levels in your blood, and soon after, if everything's OK, you donate blood (or a sample for starters). About 470ml is the norm. In Ireland, a donation can occur every 90 days. However, they will delay your donation date if you have exposed yourself to a risk of contracting something (the exposure criteria differs from country to country), or outright prohibit you. If you are green-lit for a donation, they will still test your blood for a number of things.

Aside from donating blood, there are other options as well:

  • donating the platelets which is likely possible even if you're unable to donate blood. They are used for treating bleedings.
  • donating the bone marrow. Mostly for treating leukemia patients and anyone in need of it.

Platelets are usually donated by filtering the blood for it and you have to have both arms connected to the machine. For the bone marrow, there are two ways of obtaining it. Either through direct removal from a hip bone, which requires you to stay in a hospital, or by receiving an injection with a medication that increases the production of stem cells. The stem cells get into your bloodstream and the highest concentration of them occurs a few days later. You are supposed to come in at that time and get your blood taken normally. They usually call you when there is a requirement, so you only get registered once and wait.

The ultimate thing you can do with your body in this respect is the organ donation. While you can give a kidney to someone while you're alive, most organ donations happen posthumously. Some countries implement this as part of an inclusive policy, where one must formally opt-out. That is a good approach in my opinion. If you happen to live in a country where you must opt-in, you can do so if you wish. A transplanted organ can save a life.

I hope I convinced you to make a difference. The procedure for blood donation is not that big of a deal and you get a small free health check-up. You can already start planning today.

Fairphone 2

Like I said in the No subject post, I had to get a new smartphone. My old one broke down completely so I was considering the options. Since I'm not an avid phone user, I wasn't that concerned with hardware performance. Other factors were important to consider, namely the support, openness and manufacturing process. In the end I got the Fairphone 2 and I'm pretty much satisfied with it. So why did I choose that one in particular?


Having access to support would mean that whenever there was a problem, I could turn to the manufacturer for help. But good support is not the only thing that matters; there are also the product's longevity, repairability and modularity.

Fairphone 2 was designed to have as long lifespan as it was possible, meaning that the components it incorporates are as durable as they can be. To further enhance the longevity, the phone was made modular and easily repairable. When it comes to all the fine electronics in it, parts can be detached if they break down and replaced with new pieces. This is achieved through getting a replacement part from their store. The repairability is graded 10 out of 10 on the iFixit web. They market that the screen can be replaced in 20 seconds. Hopefully, I'll never have to verify this, but it's good to have the option.

Openness regards the software side. The phone comes with two versions of Android. The open one and the one with custom closed source modifications. It was announced that the Android would be bumped to the version 6 this month. Better late than never. The default OS is updated with security patches frequently so it is very up to date in terms of closing down security holes. This is something other phones have trouble with. The phone also comes with the rooting option and you can install custom operating systems on it thanks to the support of the community.

Mark Shuttleworth turned the world on its head with the convergence concept, but killed it the other day. The community took up the Ubuntu Touch, but we still don't know if it is going to take root. I have tried Ubuntu Touch on the Fairphone 2 to see how it looked like, but reverted to Android soon enough because not all the features were supported back then. The situation looks better now, but considering the announcement, it might get bleak.

The Sailfish OS can be installed, but I haven't tried it yet. I'm still considering it. It's great not to be locked within a single software ecosystem. I even prolonged the battery life by following the instructions from the official forums and replacing firmware for the phone.

However, it's the manufacturing process where the phone really shines, because all the components are ethically sourced. They track where the materials come from and what the working conditions are at all stages, from raw materials to the finished product. As for the recyclability of the product, the manufacturers have a report on it and are very invested in it.

What the phone could benefit from is a battery with a larger capacity, though, but I am not complaining. My commute is not very lengthy. I still bought a powerbank, because now I had three devices for which it would come in handy: a camera, and both Vesna's and my phone. As a sidenote, considering all the borders we were about to cross travelling, we had to make sure that the powerbank had distinct labeling so it could pass the airport security checks. The powerbank proved to be a life saver because, more often than not, we found ourselves in situations where we had no access to power. Talk about energy usage, eh?

Another thing that I'd like to have regarding the hardware is the addition of the NFC module so I could eliminate the plastics from my wallet and use contactless payment wherever possible.

Both things above could easily be done by adding new modules or upgrading the existing ones. I have my fingers crossed.

I'll finish off with two things. One is to recommend an excellent article from TechCrunch about Fairphone that is a must read, and the other is that this article is being published on Earth day 2017. Take some time to consider the state of things and how you can contribute.

Farming practices

In the current state of affairs, the primary economic sector is no exception to adopting the common mantra of the "return on investment". One of the fundamental pillars of the civilization is to have a strong influx of food, which leads us straight to the agriculture, the cornerstone of the primary sector. It is mostly due to the "return on investment", combined with the advancements in technology, that the agriculture has gone in the direction of using pesticides, monocultures, choosing quantity over quality etc., just to increase the profit.

However, doing agriculture without synthetic help can still lower the costs and increase the yield. It boils down to making choices to do so and taking other factors, not just the ROI, into consideration when making them. This is important to know because, while organic agriculture can lead to increasing the profit, this is far from the only benefit it can produce.

Aiding the biodiversity easily comes to mind. A lot of things come to mind when you're not thinking only about yourself. Environment and the ecosystem should be included in the thought process as well.

I remember when I was a kid how I learned about some of the agricultural practices from my parents and grandparents. They used a crop rotation system which enabled the natural nitrogen fixation. Approximately one third of the field was always planted with something that would bind the naturally occurring nitrogen from the atmosphere in the soil beneath. Usually it was the red clover (Trifolium pratense) which was used as fodder and green manure.


Most of the plant species used for this belong to the legume family. Interestingly, another plant that falls into this category is soybean, and even if you have no livestock to feed, it can be used as food for humans as well.

There are other tricks I remember my grandpa employing, like using empty bottles half-buried in the ground to repel moles with channeled wind noise or whitewashing the trunks of fruit trees to protect them from sun scald and, subsequently, pests.

Without going for profit, a family can usually live, vegan-style, off of food crops planted in a field. For those who don't live in the country, there are options like window farms, which I talked about before, that allow you to grow food in your city apartment, if additional options are desirable. Depending on the conditions, going for more expensive crops can lower the expenses of your household and provide a welcome supplement to the food you buy.

To recap and expand the options here:

Natural nitrogen fixation
Some plant species, like the ones belonging to the legumes family, can fixate the nitrogen occurring in the atmosphere to the soil using specialized root nodules.
Green manure
Biomass remaining from previously planted crops can be used to enrich the field when those crops decompose. Planting specialized plants like the ones mentioned above and then using them as green manure can easily double the benefits for the soil.
Pest management
Planting cover crops can help eliminate unwanted weeds and stop soil erosion. Row covers can be used to physically stop the spread of pests and such, as well as augment the microclimate for the plants you grow. Crop rotation can help control the population and type of insects in the garden, and setting up insect hotels can ensure the presence of those insects that are required for the pollination of some plants; bumblebees for instance. It is important to attract the ones who pollinate and the ones that compete with other insects for food or are even higher in the food chain. Do think about biodiversity, though.
Companion planting
Some combinations of plants being planted together can attract good and deter bad insects, alleviating the need for pesticides. It's a form of polyculture and is beneficial as is. Because plants can grow in synergy and without stepping on each other's toes so to speak, you can plant densely to reduce unwanted weed, increase the beneficial biodiversity and, subsequently, increase the yield as well. Good neighbors can easily be planted together in your own garden or field.
Organic kitchen waste, usually coming from plants, can be used to make a fertilizer. Good candidates are peels and even tea bags. Never use meat, though. It's not meant for that. The compost is usually produced in an aerated composting heap - vermicomposting for example - but other methods for composting exist if you'd like to look into them.

Humans tend to shit where they eat. This holds particularly true in case of the common practice to use human feces as manure, which often leads to E. coli poisoning that we read about in the news. Don't do that. Human biowaste is a health hazard. That said, there are mechanisms that convert human biowaste to manure. Look for information on composting toilets, but be wary. I wouldn't recommend it.

Organic farming, permaculture, vegan organic gardening are key here if you want to look into that kind of agriculture. To expand it even further, you can look into agroecology. The point is, with the problems our civilization is facing in the great extinction we're in, it is important to keep the biodiversity we have, the food chain and the entire ecosystem in equilibrium. We should be worried about the future of our food, lest we might lose it.

The species here are not thriving anywhere else in the universe, yet we keep failing the planet and need to do something about it. Frozen zoos and seed vaults like the one in Svalbard are a backup plan in case of a cataclysm, but we don't have to resort to that scenario to motivate us, even though there's a chance it might lurk somewhere outside the door we're at. We can only align ourselves with nature or we will perish.

Another interesting proof of the organic gardening viability comes from Reganold and Watcher from the Washington State University. They have analyzed some important parameters in agriculture such as:

  • yield
  • soil quality
  • energy use
  • biodiversity
  • water pollution
  • costs
  • ecosystem services
  • employment
  • quality
  • pesticides
  • exposure of workers to pesticides

It is clear that the organic way of farming can benefit the above parameters easily and it is more sustainable. Higher prices are justified because the return is greater as well.

I'd recommend a read through that article. Chances are that people tend to ignore the parameters mentioned above because of the minimax mantra I mentioned in the beginning of this article and they shouldn't. We can all live better if we put at least some effort into it, not even a lot of it.

The Great Barrier Reef

The bleaching continues. Coupled with the prospect of the extinction of the half of the species this century, the future is bleak at best.

Marine biologists confirm that the bleaching can be seen off the coast of Cairns and just looking at the images of the bleaching happening was not enough for me. I had to see it for myself.

I was on a trip from Ireland to Cairns, Australia. Because most of my attention was turned to the voyage and preparations for it, I was having difficulties focusing on writing. Hence this article comes now.

What little I could see in the beginning of March this year unfortunately proved to be in accordance with the articles I'm referencing. The bleaching effect by my personal estimate is somewhat around 65% at best where we were (Hastings Reef: -16.5163312; 145.9873392). The reef is a spectacular sight to see, but a sad one, considering the situation.


Vesna and I were snorkeling and scuba diving and took a semi-submersible with the tour's marine biologist. They confirmed that the situation was "very bad". Nobody bothered to ask about the bleaching except me, which was disappointing. Seems like people don't understand the gravity of the situation.


The normal color of the coral should veer to brown, because of the zooxanthellae, but they get expelled by the coral when it's stressed.


If the situation continues, we will destroy a system that has been here even before humans started using the letters. It just shows the effect we have had on the environment in such a short time we've been here.
