You don't need a good battery to swap. The point of the service is to swap yours with poor battery life. They send you a refurb from a previous customer, replace the battery in yours, and then send that to a future customer.

It has been pretty easy for me because they let you filter exactly which apps can notify your watch.

This is not how Apple hires.

I’m not sure if comparing introverted life to a pandemic where people’s friends and families are dying alone in a hospital is a good comparison.

I'm strictly talking about the day to day circumstances of distancing, masks, etc, not illness or death of loved ones as that's obviously an unpleasant thing at any time.
