I couldn't possibly do that - like Ana, I'd find it far too hard to get up again. At the moment, this is particularly true, because yesterday evening as I was coming down the stairs - quite normally, not rushing or taking them two at a time (I wish!!) - as I bent my right knee I had a sudden excruciating pain rip right through my knee joint, so much so that I cried out quite loudly and my DH came rushing to help me down the stairs. Since then I've been unable to bend that knee. Getting in the bath to have a shower this morning was challenging! As long as I keep the leg more or less straight, I am managing. Even walked around Tavistock this afternoon, and did some shopping in Lidl's on the way home.
