This latest column came out about a week ago but I just saw it:
https://www.nytimes.com/2021/05/21/health/coronavirus-home-caregivers-elderly.html
Includes links to and discussion about studies demonstrating the negative impacts of being a caregiver, especially a long-term one to a person with cognitive and behavioral issues. The comments are interesting, too.
Not a lot here that AC readers don't already know all too well but I always find it interesting to see our issues written up for the general public.
