Being homeless is a state of mind and your money won't help anyone. Unless you found rare occurrence of homeless man who don't want to be homeless but some serious incident in life which did that to them.

In the past I was homeless for a month. I was young at that time (18 years old). After a very depressive period of 2 weeks I started to act so I won't be homeless any longer. Today I have 3 kids and a good job. It went well for me.

But usually, you will find people who are homeless and they like it. Or they don't want to change anything in their life to make a difference. For example, here where I live there are shelters for homeless people so they can find a place to sleep, take shower and wash their clothes. Also, they can get new clothes. But most of them don't want to go there as it is forbidden to be under influence of drugs and alcohol. Also, here is easy to find a job. Even if one has no special skills, there will be always something to do on the constructions. After one month of work and sleeping in the facility which I mentioned you can easily rent something and live normally. But being homeless, you don't need to work. That's it.

> I found my high school and college biology classes to be a dry litany of jargon and diagrams, sucking the wonder out of the incredible machinery of life.

Indeed, same here. As of myself I always liked the biology but the way it was teached was always far from what could be considered as good.

For example, I remember classes about proteins. There were some mentions about protein structures, from aminoacid sequence to 3-d shape. But it was never explained what the proteins are actually doing and why they need to have different shapes. Why do we need so much of them? I remember that it was very profound experience when I discovered how complex is the molecular machinery and I started to look on the biochemistry from completely different perspective

If anyone has any understanding of chemistry it is indeed astonishing. Living organisms managed to develop chemistry in very tough conditions.

All is done in environment full of water. Water itself is good solvent for some reactions. However, in many of other reactions it acts as reagent and before chemical process is started the water needs to be removed. Biochemistry laughs at water. Another thing is the temperature. Considering human (but there are many organisms without internal temperature control, and there is much colder than in our bodies) it is only 37 deg. C. Many chemical reactions are endothermic, they require a lot of energy to pass the activation barrier. In the laboratory we can keep the reaction under the reflux, which means constant boiling for hours or sometimes even days. Another thing is the pH. Some reactions require to be done in more or less acidic or basic environment. Biochemistry also laughs at pH and all is done in 7.4 (considering human). And finally, stereochemistry. It is also very important how the molecule is oriented in space. Things like proteins need to fold in specific manner.

If someone looks on the biochemical pathways they are indeed very complex. But it is not without purpose. It is amazing.
