I too have been lurking around this thread and enjoying everyone's personal stories. I am not surprised at all at the common thread of working through the discomforts and keep on going, it keeps us young.
We crew on a fairly physically intense boat, and love every second of it. When we started racing in 2007, we knew nothing so when the skipper told my husband and me to go faster as we winched in the jib, we tried.....and tried and kept working at it because we believed we should. Our attitude from the beginning was "of course we are racing" no matter the weather, the conditions, or even our condition. We did not know any better. When we were making an important tack, my husband "handed' me the winch handle right in the mouth, and though I stopped long enough to punch the growing blood clot down so it did not keep enlarging, we kept going, and never stopped until we got in. It hurt, alot!! but I never considered wimping out or complaining. I love sailing for that reason, it has taught me that even when we are dog tired, it does not matter, because we are headed for the rocks and need to get around that tack and no matter what, we have to make that happen. and we do.
I have had a very bad neck for many years, and so I thought when I took the position of main trimmer it would really give me trouble. ... Not so, at least after the first couple races... in fact, I never feel more limber and fit than I do when we are racing regularly. So, sailing is my best workout, from working the main to the isometrics required to hold my body in place, to moving around the boat without upsetting anyone.... it all contributes to the best workout I can come up with. I only wish I could develop a fitness set up that would duplicate winching under load and working the main. What fun that would be. (I have looked into it, and the cost of even old winches is very expensive!)
I admire all of you and enjoy being a part of a sport that is so independent minded and though we are all shapes and sizes and abilities, we all seem to have a common thread of perseverance and a deep love of the quiet power of sailing, and I think in the end, that is why I can't see myself ever giving it up.
