I am often reminded of my friend Clint. Clint is a former U.S. Marine, strong as an ox, but lil ole me can bury him easily when it comes to plowing a field with a horse. One would think he could out do me in this area because of the physical workout one goes through, but the secret is stamina (physical and mental)...its not a soldiering on stamina that he was trained to do, where he could beat me hands down if we were in that scenario...when it comes to farming though, when one doesn't use a machine, I can beat him and you betcha I boast it every chance I get just to rub his nose in it a bit more (us little guys have to have a win sometimes LOL). Clint gets pooped out easily when we do a plow day, but he is not pacing himself correctly, therefore burns himself out quicker than I do.
