Well guys thx for comments...and sad fact it IS me! Took saw to friend a lot younger than me and he started it on second pull.
 I am 80 and two years ago at age 78 I could do what most 58 year olds could not do.  Then in Nov 21 I tested positive for covid.  Did not bother me until 4-6 weeks later when I had no energy, and tired.  After every test under the sun, my doc says I'm a "covid longhauler".  If you have read anything about it, effects people differently..in my case strength/energy, tiredness.  All kinds of articles about it but conclusion is always the same.."no clue".
