Words of wisdom.

like a IT guy studying bio? or chemistry? does that even make sense? O_O

It makes perfect sense if you're studying because you want to know more about stuff, because you like knowledge not because you can monetize it (that's just being spoiled by capitalism), but because of the knowledge itself. I myself like virtually any area, though I can't fully focus on all of them because there's just not time, but I'm always glad when I learn something new. Even if you don't use it, it's always nice to know how it works.

Plus, you would be surprised how much the areas are actually blended and how concepts from biology can be even applied in IT, so yes, it makes also perfect sense if you want to do it as a job. For example, neural networks, that are modeled after biological ones have awesome abilities because they can achieve high parallelism for functions, where you don't need to analyze every last bit of data (they work as function approximators) and because of their ability to learn, so they are often used in computing when doing artificial intelligence or analyzing pictures and such. They also help us to understand better how our brains and nervous systems work in general, so it's beneficial for both guy who specializes on IT and who specializes on biology.

There are more areas where they blend, such as DNA computers which use specially designed bio-molecular machines to perform various operations on input data on very low scale, not to mention that they share other traits of regular DNA, such as self replication, which makes manufacturing more structures much easier. Not to mention quantum computers, that use knowledge both from IT and (quantum) physics.

You can even use physics in IT, for example when writing various simulation programs or creating a game that uses physics, or when programming control software for some machine, it's very beneficial to understand various phenomenons, including these that you encounter in everyday life.

Simply put, various areas of science are not isolated and unrelated, they are related very well and share a lot of concepts and they help each other a lot.
