I bought two of these for my then future wife back in 2000, just before I moved to Baltimore. Brian Billick must have made a few thousand from that motivational ploy that year, and the years that followed.
My airing of grievances right now would be that my wife, after breaking her left ankle last year, broke her right wrist on an uneven sidewalk doing a community function because someone didn't show up to do it.
The surgery didn't go so well initially, but now it seems everything is set (pun intended).
I will say, that unlike last year at the emergency unit with 26 people around, some unmasked, and a thirteen hour ordeal before she was sent home, this year was different. We're 'boosted', all were masked, and she was home four hours later on the day of the incident.
Other grievances in regards to others' actions would be too much to post here. No 'feats of strength' desired
