if you are say i shouldn't even say this because i i bother people about the biological clocks let's just say though theoretically you know you're a 60 year old person but biologically because you are exercising eating a appropriate diet biologically you're 40 years old at least your immune system is functioning like a 40 year old you might have a little bit higher igf-1 you might have a little bit higher of that early cancer risk but you have a much lower total risk of developing cancer because your immune system has a much better chance of catching it and getting rid of it
