I think you can find trousers with padded knees. I think the hard bit is
getting up again as my knees now hurt when kneeling and seize up when
trying to stand! I'm very indignant about this. Screwmatics run - or
limp - in my family but at 64 I really did not think this was going to
affect me just yet.

Carpet fitters and others use trousers with padded knees... and they are
cheap too... see...
