I am not 21 anymore

My recovery time from drinking has increased 10 fold over the last decade. I can not do a shot for shot with these 21 year crowd and expect last all night long. I am lucky if I wake up before noon. The majority is definitely about 5 to 7 years younger than I. All I got going for me is the experience. Maybe a little stamina for the longer nights. Japan has parties all night long in most bars. In fact the best time to go is from Midnight to about 5 am. This where the experience comes in, I will take a nap until 10 or 11pm then go out. (Don't get me wrong, this is not a nightly event, more of a once a paycheck.) Regardless, I can't go out as much as I used to.
