This is a great topic! However, it appears answers are based on sickness and caretaking and shifted from the author's original question, "How do you emotionally handle aging and knowing that you only have a limited number of years left in your life?"

Personally, my husband and I don't associate age with lifespan.
Death can occur at any age. We live in a society where baby boomers are attending their children and children's children funerals.

How do I handle aging? With gratitude. I tell God throughout my day thank you for everything. I am so thankful for all God has given me. I could have been dead sleeping in my grave but God made old dead behave. Lord you are so good.

We all got a date with death. I believe there's a heaven and a hell and I always tell people don't let death catch you in your sins.

Like you we are fairly healthy but enjoying retirement. We choose not to work our life away but use the rest of our days doing things we didn't do when we were parenting. Road Trips!!! 🎺Jazz Concerts!!! Sleeping in! Volunteer Work! Contractors Work when we want to! We are living our best life not focusing on death, toxic relationships or rainy days and Mondays.😁

We are retired and going to live, love, laugh, eat, drink, take time to smell the roses, and be happy together until God say times up.
