So sorry to hear the news about your sister; and yes, I'm afraid that that is indeed what we might expect is the lot of upcoming generations, given nutritional and environmental degradation on a massive scale...
WOW, you are smokin'!!! Love these progress pics - you must be so proud!!
I totally empathize with your wonder at the randomness of various symptoms. The whole thing is rather a mystery, isn't it?
Way to go on the Christmas party! Sounds like you sailed right through!
