Why do you still consider any of this necessary at this point?
My wife is in her 30s and healthy. COVID can still be quite brutal, although of course the extent of the measures one should take is highly debatable and subjective.
As an aside: even pre covid I was eagerly waiting for a (somewhat) affordable exoskeleton. I am going to have the best Darth Vader cosplay ever.
It's good that she had you to rely on. I did a lot of reading on long covid and there were and so are so many people isolated because they're basically spent all the time.
