I am in early 70s now, and swim twice a week, 20 lengths breast stroke. I prefer this to walking. My daughters think I'm mad, as when I started swimming 2 years ago, I went to Sports Direct to ask for a swimming hat. I had in mind the one I used to have in the 50s, it was lovely with petals on and a strap under chin which really fitted well. They looked at me with amusement as though I was demented and showed me the modern ones. I bought one but what a disappointment, its like half a balloon, and as I have longish hair and a bun, I struggled to get it on, and then it gradually came off, so now I don't use one, I swim with head out of water as I don't want to get hair wet, its difficult enough to keep it coloured.
