I did a few years ago, and it was rewarding...but it also drains one too.
The turn around rate for some is 4-5 yrs, depending on the work.
Men are not as common in the job, and you hear-see just about it all.
Not a perfect job, by any means....but one that is very much and always will be needed.
I could not have lasted much longer, and was very happy I sold my house...and moved to Sydney, to have a new start with Job and home.
Even if I was 10-15 yrs younger....I would maybe think twice now, if I wanted to do that job again.
