Home: Just about three weeks to the day; can't fault the NIH for estimates.

I'll write more about the experience in the next week or so. Right now, I'm just beat. Slept about twelve hours last night; haven't had more than four consecutive hours of sleep since my stay there.

As usual, the staff of NIH was mostly very good, sometimes great, and unfortunately worthless a time or two. Still, deeply grateful for this opportunity.

More in a few days...
