I "know from experience" myself, but I thought these guys were immortals:)
They are all wimps :-)
Personally I am having a bit of trouble walking from the sofa to the fridge this day... It feels like a category 1 climb.
Cheers.
I know that compared to me they surely are but, it's all relative isn't it? Their hill is my mountain, etc. I have felt the humiliation of being passed by a butterfly on the slopes of Mt. Mitchell. I have been awed by the power and speed of these guys up Brasstown Bald. They feel the same level of pain we do, it's just that they are trained and paid better than we are to deal with it:)
