,,If the average life expectancy is ~80 years, my parents are in their mid-60s, and I see them one time per year, the math—however depressing—says I will see them 15 more times before they are gone.''

I'm right now on a vacation with my mom, but it's not the same as when both my parents were alive (a year ago).
