I think that's about right. And, I'm in the 65 to 75 year cohort. Maybe... May.
I got you beat pardner. LOL... Turning 81 in a few weeks.
But I really do believe keeping lungs in top shape is the best defense against any respiratory virus such as covid-19. So I am doing 6 days every week treadmill fast walk.
Besides I am now 99% certain both me and wife got the infection during Carnival cruise ending on Feb 29th 2020. Both had minor symptoms after disembarkation for a few days. That is better than vaccine to build future immunity. I have visited various stores 75+ times since last February. There must be a few covid-19 cells floating in Walmart and Lowe’s and Aldi’s. But not even minor symptoms so far, knock on wood. I must be reinforcing immunity continuously with mild exposures hahaha.
