I've been in strict lockdown for about six weeks (apart from strolls in the park for 15 minutes when there are very few people around).
I decided today I would do 'essential shopping' myself. Out comes my scooter, I go to the bank, butchers, bakers - all together about 40 minutes (one in one out)! Back home I struggled to lift, entered the bedroom and collapsed on the bed. That happened 1 1/2 hrs ago. I am knackered!!!
The moral of this story - just don't believe getting "back to normal" is going to be a doddle. Obviously things don't 'work' as we expected them to.
