Regarding covid, will life ever go back to like it was before,with no masks or worries about getting sick every time you go out? i wonder how long that will take until we can do normal things we did before without thought, like concerts or parties?

Life is always changing and it was always with worries and infections; just different types of infections. Covid is in the family of common cold virus and we always had common cold and influenzae. You should continue to do normal things with precautions. It is important to wash hands and avoid putting contaminated hands in the eyes and mouth like we were taught all along. Covid is here to stay.
