You don't see marathon runners or triathletes dripping with sweat. It's partly due to their low body fat - fat bloke in the pub sweats just picking up a pint glass.
Not at all - I am aware of how the body responds to exercise and an increased temperature.
I am referring to excessive sweating which can be experienced by those who are not particularly fit of which I wouldn't classify Glenn Murray which is why I wouldn't expect him to "break into a sweat"...
