What is worst thing for an elder? Going back and forth between kids or staying on her own in al?

Lonely elderly. Most elderly are comfortable in their own home, unless cognitive , memory change cause harm to themself or others it is an individual question, which they clearly know the answer.
I agree. A family discussion needs to occur, but the elder should have the final say as long as he/she is able to safely stay in the home and has no mental impairment.
