Yes - It is a reminder of how we need to take particular attention with our backs. Pinballs are heavy bastards, and they might look light, but sometime the way we move them can be cumbersome and lead to trouble. I looked after my back and participated in the recent Container days at Child's and I was fine... But even a simple task of leaning "into" a cab can put strain in a particular area.. You don't have to be lifting anything..
I've been confined indoors this week and I've decided to do some board repairs.. Hopefully, I'll be able to sit down rather than lie down or stand up..
