Personally I think you should be OK. You won’t have to isolate. We’re just in a Tier 3 adjacent to Tier 1 so we have to go through both a lot for work and shopping and obviously don’t isolate! In my Tier 3 area there are very few cases - but the whole county is in Tier 3. Our nearest amenities however are in Tier 1!
The government changed women's pension age and called it progress. Did anyone actually ask you?
