In fun developments, the “Becoming Brad Pitt” dialogue with scientist Raymond McCauley about MTHFR led to coverage in Nature Medicine. His help was invaluable during testing (and doubly so during interpretation), which made his e-mail all the more wonderful to receive. It began as follows:


Since we last talked, I’ve been doing more work on the MTHFR project you’d suggested. It’s started to bear some fruit, as well as coverage in Nature Medicine

I haven’t outed you as a participant, as you’d requested anonymity for all things genome related — but would love to if you reconsider.

Pretty damn cool stuff. My answer was: of course I’ll reconsider! Raymond and I will be doing more together and reporting the results. Are you beginning to see how exciting this process of discovery can be?!? I hope so.

It doesn’t require a PhD, and it doesn’t take a lot of money. It requires an inquisitive mind, a good hypothesis, and a willingness to test the uncommon.
