He was wealthy but retired and physically fit with time on his hands so he decided to start doing his own mowing after 50 plus years of paying others to do so. He bought a new lawn tractor as he had grown up farming and knew these things. He was also a licensed pilot.
But he suffered from Alzheimers.
morning he would walk out and survey the tall grass in his yard, get
the mower out and mow the yard. And the next morning he would repeat the
process, day after day for weeks on end never realizing he had failed
to lower the mower deck.
Finally my aunt called my Daddy and told him where to find the key to the shed while she took my uncle out for a few hours.
This process would have to be repeated every week or so in order to make my uncle think he was mowing the yard.
