the best knee pads are the ones the apprentice is using, saves on my own knees. Have to say this having been off work for several weeks with back/leg pain that was so acute me and the ambulance crews were on first name terms after 4 trips to A&E, and v large doses of morphine and entonox to cheer me up. Eventually after a very long needle in the hip ( they use the same needle for wide thighed woman as skinny plumbers) and yes it hurt pushing in all that cortisone, the leg no works a bit. Now after a visit to the consultant it's another smaller needle to the knee and maybe I can start installing systems again rather than only being able to repair wall mounted boilers!!!!!!!
So to all of you out there, only 52 and they knees and hips are failing badly, moral don't play rugby, avoid joining the army or navy it hurts to much, I dont think the raf do anything too strenuous though, spend to much time on the floor on your knees unless working for a living (think about that one), dont lift 2 cement bags at once, it blows your cartilage very quickly, and always have apprentice or if you cann't afford one the very best knee pads available, they are replacable your knees arent
