My son (at college) and I were on the phone the other day planning a summer hike/climb together that he is arranging. I was grilling him on the details on level of difficulty, terrain, number of hours we'll need to ascend and descend, equipment needed etc.

At one point he said, "Jeez Dad, relax, you're in better shape than I am anyway."

[BTW, my commute is only half the distance of Unixpro's]
