I'm going to do a bit of traveling and needed to get 5 shots today. The nurse asked me which arm was dominant -- apparently the hep and typhoid shots cause more discomfort, so she wanted to do them in the weak arm. I told her I'd just as soon have them in the arm I use more.
As soon as she was done, I immediately regretted not asking her to put all of them in that arm -- the main reason I didn't was she told me I definitely needed to use both arms.
I'm not saying that shots hurt, but it occurred to me that I consistently tend to seek situations which introduce discomfort. For example, I'll choose to pour alcohol on open wounds rather than H2O2, even if the latter works better for disinfection. I won't take prescription painkillers even if I feel really bad (the worst I had to deal with was 2nd and 3rd degree burns, and that's something I wouldn't wish on anyone).
Especially when I see what some roadies will do to themselves. I suspect I'm very mild compared to many. I was just wondering how many people actually seek a little pain from time to time.
