Memory issues aren't age dependent( @Matt.Cross will like this story) buddy was a Tool&Die apprentice and had made up some tools( 1-2-3 blocks, angle plates and parallels. After heat treating them he buired them in the yard for stress relief prior to grinding. Over time he forgot about then but his dad found them about 2 years later... with the rototiller as he decided to increace the size of the vegetable garden.
I don't know about owl $hit but Canada goose $hit pretty slick...
