Brilliant, Mons.
Thanks everyone and my apologies for not replying sooner. I went over to my daughter's new house yesterday to try out the pool there and finished up falling backwards and hurting my butt, shoulder and upper arm and badly grazing my elbow so now I am finding it difficult to use my right arm. I hit my head, too, but that seems to be OK.
Anyone else would have fallen forwards into the pool but stupid me had to go over backwards !
