Today we know many aspects of our history and why did we developed some features and abilities. Scientists learn everyday how we evolve to fit survival and progress. The bald guys are genetically more evolved than the hairy guys and that’s because now we have roofs over our head and we don’t need hair to protect our skin. In other areas like food supply and the means to get it we evolved too fast and our bodies didn’t have time enough to adjust. We got fat because it’s easier today to get food. Of course a kid growing in a poor area in Africa would disagree but mostly today is much easier. Our bodies are getting used to more dangerous viruses and bacteria. But things are changing faster and faster and that makes the gap between our biological evolution and our habitat evolution bigger and bigger. An example of that is the solar protection factor we are using. In the 60’s that didn’t even exist. I remember in the 70’s my mom using tanning lotion with no protection and lying at the sun at noon. Today if i do that i’ll use solar protection factor 45. In twenty years it’ll get to more than a hundred just to go to work. Our bodies didn’t have the time to adjust to that. I wonder what will happen in the next hundred years. Things are changing really fast. I remember when i spent 5 hours on the internet in the 90’s. My dad told me i was crazy and i felt really dizzy. Today most people as myself use to spend more than 5 hours a day doing things online. And we are getting fatter and lazy. I’m lucky for not being really good in predictions. I would not sleep thinking about what we will look like in a hundred years. I hope this curve changes and things get a little more healthy.
