Cold water swimming

A short time ago, I did some cold water swims at Pells Pool, Lewes; an unheated and spring-fed with minimal chlorine. Water temperature reached 12.5 C. In normal indoor pools it is around 25 to 28 C. Cold water benefits mental and physical health and on 19 October this appeared "Could cold water hold a clue to a dementia cure?" Segue to Beckenham Place Park we have the Beckenham Bobbers.
