it's a horrible analogy but one could compare this to sex. you will always remember the excitement, nervousness and rush of your first time...maybe even your second or third. I bet you dont remember your 20th, 100th etc... I would wager that if someone got into LE solely for the adrenline moments then they would be sorely disappointed.
Whoa whoa whoa whoa.....sex is WAY more fun than catching criminals and actually gets more fun with time. Catching criminals gets LESS fun with time
