Dr Azar, your comment that grandmothers aren’t that useful after they turn 75 was rude, insulting, and hurtful. My grandmothers were a blessing to me long into their 80s. I am nearly 70 and have 10 grandkids. I plan on being a loving, productive part of their lives for many years to come. If you have a grandma, I hope you will apologize to her.
