Theresa, you have the credentials, so join in. Nothing unworthy about it. I like your attitude which parallels mine. When I was a kid I cleaned the manual typewriter (remember those, people?) keys with carbon tetrachloride, which is now known to be a carcinogen, but I didn't drink it. Bottom line, who cares why, when all is said and done? That we are here is what counts.
With regard to stats of reoccurence, they are an AVERAGE. I am definitely not average and in fact no one is, so that is how much weight you should give to them. I am too tired to get up on my soap box about this, but remember that time spent worrying about something that may happen, is time wasted, that could be spent in happier pursuits. If there is a reoccurrence, then worry is justified. Just go to checkups, live a healthy life, and have some fun.
