I can swim, but never particularly enjoyed it or was particularly good at it. I dislike the whole process of stripping-off, climbing into a costume in an inhospitable cubicle and then making my way to the pool (which is always cold). If there were no more than 2 or 3 others there it would be OK - but you can't move sometimes and get splashed in the face, which I hate.
Having said that, before lockdown I had been going swimming regularly for a year and managed to swim half a mile - it helped my spine which is a bit damaged. I can't raise the enthusiasm to do it all over again and it has become much more expensive.
