My college roommate freshman year liked to give blood and then get drunk.
It's not recommended. She liked it because giving blood lowered her baseline. Her tolerance was lower and she could get really drunk really quickly.
Along the same lines I am sooo happy today. On my return it would seem that my life baselines have been lowered. I am euphorically ecstatically giddy. Because, today, I am not in a cramped moving vehicle, I am not sitting for hours twisted like a pretzel, I can stop what I am doing and go to the bathroom anytime I want, I got 8 hours of sleep last night in a bed and I plan to get a bunch more sleep tonight.
Indeed, as Ace of Base might say, "It's a beautiful life."
