It's hard. Peronally, I still am not comfortable in crowded indoor settings and have had a few people I know get very ill due to Covid recently. One is only 38. So, the threat is still there. All any of can do is assess our own personal risk factors and do the best we can. Hopefully you can figure out what's best for you without feeling pressured by others or comparing yourself to them too much. We're all different in the level of risk we feel comfortable with taking.
