I'm 40 and have similar health issues as my 95-year-old grandmother. I look to her for strength.

• My grandmother is 95 years old, and I'm 40, but we have the same medical issues.
• She isn't slowing down even though she's a superager, so she gives me strength.
• We rely on each other during this time when our bodies are changing.

"What did you do today?" my superager grandmother Rosine, nicknamed Neni, asks me almost as soon as she picks up the phone on our nightly chats.
