Colin, so very true. I myself am recovering from a workplace related incident and have been hobbling around since early Dec 2015. We often take for granted our own mortality thinking that it will never happen to me. All too often we will follow the rules at work, only to break them at home, knowing better.
It is all too easy to be impatient, perhaps it's a man thing. I don't need help, don't be silly, it's not that heavy... Too little, too late after the fact. If you don't get it done today, get it done tomorrow and bring a mate to help!!!
Get well soon.
