I couldn't hack going back to work again Shaney. Apart from not being able to cope physically, I just wouldn't react kindly to be answerable to anybody!!
I saw the programme. I think I would trust an older master craftsman, eg carpenter, probably more than a young person. Young people are faster and catch on quickly and more physically able but older workers are often more conscientious and want to do things properly in my opinion.
And no, I would trust that particular nurse, but there might be others of the same age who would be excellent.
In other words I don't think age is necessarily the criteria for the workforce. The are fit, mentally alert old people and unfit, slow young people and vice versa.
I have a husband out there today putting on our new garage roof and who is just as fit and active as he was 40 years ago. I would trust him more than some builders!
