First things first. I actually woke up my roommate because I cracked up proper quite a few times reading what you wrote. I love your tone, wonderful!!
The craziest thing I have ever done is - a few years ago I almost got shot right in the head by this utterly handsome guy with alarmingly high sociopathic tendencies. Almost, LITERALLY stared down the barrel of a gun. Point blank. LITERALLY saw his fingers twitch on the trigger. Said my prayers and bye bye to the world before getting miraculously saved by someone I now hold very, very dear to me. It may not be the "wild" that you would ever voluntarily experience just for the sake of letting your adrenaline rush go nuts, and it's not the happy crazy memory that you would ever want to recollect in front of a warm fire many many years later to your grandchildren.
It was crazy in terms of it's insane magnitude - It was a tremendously disillusioning experience for me. There is nothing that I refused to learn from it... the fragility of life, the importance of each of your decisions, their dominos effects and their consequences, the meaning of real danger, and the true demonstration of "your life flashing before your eyes." It was all the wrong kinds of wild. But it's changed me more than perhaps anything else could.
I try to make smarter decisions, be less impulsive, appreciate life more, and avoid questionable actions and people like the plague.
How amazing would it be that your wildest memory is not only that, but also your most life-altering and scariest one also?
Are you ok? This sounds very scary.
I wish mine was somewhat like yours and that I had the same humor that you've got (much love). But yes, it was quite scary. But I'm perfectly fine and incidents that mark a certain change in your life are usually most cherished - whether it was accomplishing something, making a crazy move, or getting in trouble - they should always be welcome. :)
Oh and yes! 50 is the new 30! Age is just a number, and we should never let it undermine us as a person. If you're eccentric and crazy and fun-loving, you should be all that even at 70! :D
