temperature is also a environmental factor, a slight change in body temperature could have huge effects on protein function and enzymes, just like a slight change in pH. Why don’t you focus on temperature then? It could be the answer to all your hypothesises! When you get older your average body tempature drops, so we are all getting colder.
WCF, yes, I included it in internal environment factor (pH, temp. etc.) in some of my posting on reproductive system/sperm's production. I was thinking it to take up next time as it looks pH & temp. can both be inter-dependant or inter-related. In enzymes/hormones/gemete making & working--Optimal pH & Optimal Tempreture can be more relevant. However, I am trying to understand that which is basic in these two. Can you indicate something? Can damage to genes/genetic code possible by some tempreture imbalance?
