OH sounds as bad as me. 
We would get on well. 
The problem is that any help that you get is next to useless! By the time you have explained things, waited for them to stop texting friends or making phone calls, dropped damaged your tools, you may as well have saved the money and done it quicker and better by yourself.
The downside for me is that I am only 44yrs years old and already have to lift my legs out of bed in the morning, and sit or lay down just to put my socks on. Probably just like OH, my knee and ankle joints are also very much the worse for wear.

I recall the joys of training an apprentice, and that was before mobile phone distractions.
By the time they are of any use they qualify and leave.
And they call you a miserable old **** if they are out of arms reach.
