I live in New Zealand and we have, for the last month, been living in our 'bubble'. A bubble consists of those people who live in the house and just those people. My children live in other parts of the world but if, eg my son, his wife and children lived a quarter of a mile away, my bubble (my DH and I) could not visit my son's bubble. We may be part of the same family and could say 'but none of us have the virus so surely we can visit' but the order was no, we couldn't. It has been very hard on families as it has on families in the UK and other countries who have had the isolation process. As far as the 70's and over age group not being allowed to go to supermarkets, it's not that we are 'not allowed' but it's been stressed all the way along that if my age group do visit a supermarket we must do it with the utmost care but if possible, and very much preferred, we should try to find somebody else to do our shopping. If someone doesn't have anybody to help them there are organisations who will assist. We go into Level 3 (probably but not yet definitely) on Tuesday night which will allow a little more freedom but there will be very little in the way of shops, hairdressers open. If a business can arrange 'click and collect' or some other way of paying without contact then they may trade but there won't be any actual shop buildings where people will be able to walk into. We are just a little nation population-wise and my heart goes out to countries such as the UK where there are so so many people.
