But seriously, I am in my late 40s and have always had a very healthy lifestyle -- good weight, exercise daily, eat tons of fruits and veggies, no fast foods. I don't drink, smoke or do drugs (well, maybe one puff in college ...).
I am a believer of genetics AND the environment interacting together. Our bodies are soooo intricate. If one Lego is out of place, it changes the infrastructure. Perhaps there's a virus that begins a downward spiral or chain of events to the immune system. I remember in college getting very sick once and then I started getting cold sores (so I guess that was my exposure to the herpes virus, HSV1). Shouldn't have taken that puff!
But many people are infected and don't get multiple myeloma. The only other thing I can think of for me, personally, is that I love gardening; but I don't use any pesticides other than Roundup, oh, and we do get our lawn treated. But, again, so do many others. It would be a relief to find the trigger, but I think there are many needles hiding in the haystack!
Some day ...
