Hammer, drill, sawzall.....seriously
Friend of mine once had his kidneys replaced with one from his mother. With local anestetic, so he could watch and learn.
Yesterday, I towed a large Kinetic Kontraption with four people... a bit over a mile, on the water -- with my one-man amphibious tricycle. Took a little over an hour. I poured most of my drinking water on my straw hat for cooling. Afterwards, my right knee was almost twice the size of my left. Yes, my right knee is my "trick" knee from a traffic collission some 35 years ago. Life is good. Stuff happens. Life remains good.
