Oh, I dunno... I know of a couple of blokes who've managed to regress to the diapers, bibs and mashed food stage. :rolleyes:
I know I can do the same work that I did as a lad - better and faster at that! The "trick" is to work smarter, not harder. However, there're some jobs that cost me afterwards no matter how "smart" I am about it. I gave up flooring when, every day for a week, I had to crawl out to the car at knock-off 'cos I couldn't stand upright. And that was with all the flash tools that reduced the need for bending over or kneeling down. :sigh:
I'm blowed if I know how my ex-boss managed to spend his whole life doing it, working well past retirement age... :no:
