I agree. I'm 60, smoke, drink, asthma I've had Omicron once that I know of (3 days I was fine and all up it wasn't too bad muscles pains on day 0 was not so good) maybe twice as I had head cold symptoms not long ago (pretty mild, milder than previouis over in 2 or 3 days) and not sure but I think I had Delta a couple of years ago. That was worse and lasted about 4 or 5 days but still wasn't much worse, if at all, than some colds I've had in my life. Jabbed twice with AZ last time Oct 2021 so my natural immunity should be good. I'm not concerned at all. The point that can't be ignored is that experts globally describe Omicron as not severe for those classified as not at risk. I will never get jabbed again and as you know I don't wear a mask. I should say that with Delta I wore a mask as Delta was not good but since Omicron booted Delta basically from the face of the Earth I haven't. It didn't take long for the evidence that Omicron was less severe and even now the new sub-variants are even less severe than the original Omicron.
