Any way to keep grandmother social distancing?

Hey guys... so my grandmother refuses to social distance or wear a mask. She says she will just to placate my mother and I but never does. Has people over and hugs them, never wears a mask and goes out all the time, goes on long car trips with her other daughter and adult grandkids (who are also not social distancing), etc.

I’m looking for maybe gentle but persuasive arguments for it? She’s 80 and in poor health already. Says stuff like “if God decides it’s my time to go then wearing a mask won’t change that”, etc. I just don’t know what to do... we’re so worried for her but she thinks it’s ridiculous.
