I’ve been very healthy. Received the vaccines and boosters. I think after being in “lockdown” in 2020 and part of 2021, people weren’t going out and spreading the normal colds and respiratory diseases, etc., and our immune systems weren’t getting built up. Then when things returned to normal and we were around more people (and spreading germs) everyone started getting sick. Yes, aging has a lot to do with it. Sleep, eating healthy, washing your hands & exercising are important for our health.
