Its funny, when I was in my 20-30s I used to get a good dose of the flu every year. Now, in my late 60s, I don't get as much as a sniffle and have not really had any flu/colds for 20-30 years. Went straight through COVID with nothing. Not sure what to put it down to. Not a big socializer and am retired these days, but I shop and come into regular contact with people like everyone else. I have gotten a flu shot and COVID shot at my wife's insistence for the past 3-4 years.
Watch now, before sunrise I'll come down with one or the other.
