personally, i can think of things that happened to me that didn't happen to my siblings, concussions playing football, getting chicken pox in my 30's, taking a systemic medicine for toenail fungus, working in a research lab with a lot of organic solvents, worked in ag research around experimental chemicals, the list goes on.
maybe just one tainted meal?

Scientists recently made a huge discovery that explains why this happens. Hmmm...thought I posted it here. The gist of it is that once scientists considered "junk DNA" is actually the a switch system that controls how cells, tissues, and organs interact and behave. In other words it is not a mutation itself that causes disease but rather this switch system that modulates how our system reacts to environment. In essence, it neatly explains why one twin gets PD while the other goes unscathed.
From the report:
The discovery, considered a major medical and scientific breakthrough, has enormous implications for human health because many complex diseases appear to be caused by tiny changes in hundreds of gene switches.
The report:
Far from "Junk"DNA...
Oops, forgot to share it after all...I was preoccupied with trying to impress a biologist.
Well now you know
