I run a plumbing and roofing business in Sydney…One of my guys is 74years old who I knew when I was an apprentice back in the bush. This guy still turns up 6 days a week and can go up and down ladders all day … old school tough … Last few weeks he has had sore knees ( fluid I think ) … I put a patch on him last week for a day and he can’t believe the pain reduction. He’s just asked me to buy some more for him. He’s already taken most of the ones I had. Really need some promotion for this. He’s said he’s happy to do some modelling if required!! on a good thing here IMO..
