Wild swimming

Weather: 22C at 10pm.
The warm humid weather today brought out the wild swimmers up at the reservoir.
 
Among them were three regular women swimmers whom I recognized. Their swimming is impressive; they traverse the breadth of the reservoir and back again. (See extra).
 
 I just wish I had the confidence  get in and try it. Apparently cold-water swimming boosts the immune system but you can get a similar, if much smaller effect, by taking a cold shower every morning. Somehow that doesn’t appeal either.
