I haven't been 'n town' to visit the shops since March. Today needed some bits and bobs so popped a mask on. I'm asthmatic and could use that exemption but thought I would give it a go. I was really surprised that despite numerous signs in shopping centres etc that probably around 50% were wearing a mask and 50% not. I was really surprised. Mainly younger people but a few middle aged. In the main the elderly were wearing masks.
There was a group of young people (between 18 ish and mid twenties) wandering along together and not one of them bothered. I know that the virus doesn't tend to affect them much in the main but was quite surprised.
In my area - low population - there have been no deaths at local hospital for around 22 weeks ish and no-one in at present (SIL works on MAU/ICU) and infection rate really low anyway.
AIBU - a lot of young people are exempt so why should they wear one
YABU - 50% of people are exempt from mask wearing
YANBU - They are just bored with it all and cannot be bothered anymore.
