I am interested in stomach acid and heat expansion, for instance the stomach will become heated due to an athelete competing. The heat causes atheletes to live shorter than people who don't have their body heated so often. I do a lot of differential equations and number theory, but I was wondering if probability theory could help with this. What do you guys offer in this field that has to do with that?? The only thing I can think of with probability theory is that they have methods employed in their fields rather than something concrete like number theory..
