Concentration problem

TSA BBQ @ Bald Eagle 2010

I have difficulty concentrating on my research since two weeks ago. More precisely, it is after I gave two consecutive talks on one Friday. That really drained my energy out.

I missed the old days that I could play baseball in the afternoon during weekdays.

Okay, I have a poster presentation in mid-September and AICHE in mid-October. No time for hanging around.
