Another birthday has come and gone. I don't feel that old. But it definitely takes me longer to recuperate from trips that it used to. I had a good day today, with lots of intense conversation at work. After about 4pm, though, my mind went black. The rest of the evening was spent trying to motivate myself to do something productive. I failed. You know that sensation you get when your foot falls asleep? That's sort of how my brain feels.
