Totally irrelevant in this case. If there is tangible evidence, i.e. the chemical composition of the sweat is different then this is not a matter of faith.Originally Posted by green_willow
Even if the physiological function is different it should show up in different comparative levels of hormones, etc.
However, I do find it hard to believe. I think it is subjective. Different activities make different demands of our bodies. I would love to see the evidence, but I don't feel I need or should badger TCB about it.
