I’m 68 and had a quad by-pass in 2020 and I am not vaxxed.
Work in the yard, re-roofed my big tool shed, do all kinds of stuff. Even with Florida’s high heat and humidity!......................
I am 83, had 4 jabs starting more than 3 years ago.
Still mowing lawn with push mowers in 86F weather in FLorida.
No heart problems, no lung problems. Also work on my cars to change oil & filter, maintain my central A/C unit, and all yard work to maintain grass & bushes. I think it is the daily treadmill keeping me going strong.
