ahhh memories. I was born in '51... I recall ;
-jumping off the roof once with an umbrella... (soft landing thank goodness)
-scuba diving (so I thought) in the fishpond...
-digging a deep hole in the backyard and crawling in.
-It was dark so I filled a tin can with rolled carboard .....
soaked it with melted paraffin...and lit it in that hole in the ground....dang near asphyxiated myself...
-my dad taught me mechanical engineering... used to challenge me to take stuff apart and put it back together from my earliest memories. worked
