Pretty cool how some people can work around feeling old.
Back when I worked constitution in Milwaukee WI, there was this old carpenter , Hank, from Fiji. He was missing a bunch of finger tips and 76 years old last I saw him. At 76 he would work all week on his hands and knees or up a ladder above his head, filling in capitals for concrete deck forms for towers. He liked to work, and he knew what he was doing. I sure would like to be as agile at 76 as old Hank was. Not likely though.
