You are so terrific to remind me about Shingles. I am 67 and saw my elders go through shingles so I was early in line for the vaccine and have had it. No picnic that. It is fortunate they can treat it if caught early now (helped with both my mother and my husband) but the vaccine is the ticket for me!!
I do swim in our lake, Lake Anna, Virginia. I do not do laps, but swim from dock to dock sometimes. I also kayak, paddle board and jet ski. (Jet skiing is supposed to burn lots of calories, but I sort of doubt it does!) Our lake is very clean and lovely to swim in. And when it's humid, it's the best!!
I like the beach too. We go to North Carolina for a week every summer. I do not often swim in pools.
