I am getting too old for this...
"This" being pretty much everything it seems. Earlier in the month I was out in Hawaii, and apart from hiking up Diamond Head (~45min and almost killing myself) and walking about, I did not go exploring like I used to. And just got back from Miami a few hours ago, and that was pretty much a bust in terms of tourist-y endeavours. I guess going out to parties two nights in a row is a bit much. The weird thing is that I couldn't fall asleep at all once I got back to the hotel (4am and 5am respectively). This ridiculous second wind has got to stop somehow. Oh well, hopefully I can revert back to some sort of normal hours soon.
