I always say that I am 1 dust bunny away from living in a bubble! It's not so much that my immune system sucks, because I think it's not too shabby, but the fact that last year I had a DEXA scan and was told that I have osteopenia. I then thought drinking 2 big glasses of milk a day would suffice. Needless to say I was in real pain, there's nothing like being betrayed by your own body. I feel like I am decades older than I actually am. Because of my lack of taking calcium/vit D supplements, I have probably progressed to osteoporosis. I now take CitraCal, and have been doing so for a few weeks.
