About anytime I grab a wrench to work on my tractor, or anything else I end up drawing blood. Most old folks like me know what I'm talking about. As we get older our skin is not as tough as when we were younger. Yesterday I stepped on a nail that went through my shoe into my foot. I always thought a nail in the foot was about as bad as it gets, as far as wounds go. I did some checking on the net about Tetanus. I found I have 24 hours to get a Tetanus shot, or I could get lock jaw and a number of other dreaded things then die. I didn't want that to happen. My last Tetanus shot was over 20 years ago, so I got my shot Tetanus shot today. I don't know why a nail is worse than knocking off some skin some place else, but Ialways thought it was. Do any of you keep your Tetanus shot up dated? Stan
