If you scroll to the right hand side of this image you will find the "Iron Man". The "Iron Man" is a Russian volcanolgist who is in his 60's, the "Iron Man" can hike over 20 miles in a day, gaining huge elevation, and the "Iron Man" will smoke 2 packs of cigarettes while hiking the 20 miles. I wish I were in as good of shape as the "Iron Man", and I am only 36 years old. I have trouble imagining being in that kind of shape at 60.
