Lumbago

[TimberWolf]

turns out sitting with a straight back is not the best position. Phew.

BBC News - Sitting straight 'bad for backs'

IMO you need more than one slouch position though. Be a fidget.

True, but what about obesity, high blood pressure, DVT etc. etc. You can't win.

Yeah, but they don't hurt.......

ALthough I am riving a fecking 9m motorhome to France in 2 weeks.

Lumbago in a Winnebago, bummer!

Since I've had a seat where you can sit back, have had less back problems.
