In crowded busy places - yes.
Not so much because I'm worried about me (40 and double jabbed and should get booster in autumn as ds carer) but because I don't trust others to be sensible or isolate if not double jabbed etc. I don't trust people to continue LFT or testing for symptoms.
I don't want to risk catching it (yes I know it protects others more than me but it is more protective than no mask).
I won't wear one when passing through indoor areas if I don't feel it busy etc. Won't worry about wearing one to walk through a pub/restaurant if not crowded etc.
But I'm not comfortable with going from all to nothing in 1 day whilst cases are rising as they are.
