My friend Sam is 99 years old.
Does he look like he is 99?
He does and he doesn't smell very good either.
While it is good that you are friends with someone who is elderly, it's wrong to that they smell bad. If your elderly friend has trouble bathing, you should get your friend assistance so that he can wash himself properly.
I think you are right, I will call the doctor in the morning and see if they can send a home health aid right away. I will also talk to him about it too.
Its nice of you to do that for him. If he was still left to do that on his own he could have died from neglect. You are a good friend to him.
