I am going to put it on the wall some time. I experienced it so many times. I did things way back when nobody else did them, kind of like the country song, "I Was Country When Country Wasn't Cool".
Made gunpowder when I was 12, handloaded ammo when I was 14, was in bomb disposal, lived on sailboat, sailed half way around the world, bicyle ridding, hiking, camping, and fixing to start flying.
When you get old and let your dreams die, you die right behind them.
