Bee and I are lucky enough to have all 4 of our parents... but they are anywhere from 60-80 years old.
I don't know what the actual actuarial tables look like, but I'm guessing that every year there's a 10-20% chance of one of our parents passing away. It's really sobering, and has made it easy for us to really prioritize spending a lot of time with our parents!
How old are your parents?
