Praa Sands is a beach about one and a half miles long on the south coast, between Porthleven and Marazion. I stayed there in a caravan with three of my four children back in 1991. We walked miles along the coastal footpath as I didn’t drive then and bus fares were very expensive. I was the same age then as the son, who is staying with me, is now. Oh, how I wish I was that fit still. Nowadays walking is still enjoyable, but the aches and pains in the joints afterwards is not.
