I flew 500 miles and back yesterday.  Sadly not to Boston, though I would not have had time to see anyone anyway, I had four appointments in various towns where I was.

Oof tired.  Flying takes a lot out of me in general.  Trying to drink a lot of water today, dehydration is part of the equation.

Someone I know through my job has DVT.  I don't think I fly enough for that, but then, he didn't think so either.
