For much of your life, when you look far into the future, it's almost always to a time when you're still likely to be relatively healthy and active.
Like, for example, when you're 20 years old and set goals 30 years down the line, you're thinking of the 50-year-old version of yourself. That may seem pretty old to you as a young adult, but those of us who have passed that age know that 50 is still a time when you have lots of energy to do the things you want to do.
Now, however, when I undertake that same mental exercise as a 55-year-old, it's a little different. In 30 years, if I'm still blessed to be around, I'll be 85.
Suddenly that 30-year projection takes on a whole different character. While it's true that age is just a number and you're only as old as you allow yourself to feel, 85 is still 85, no matter how you slice and dice it.
Unless you were around in early Bible times when people apparently lived well into the triple digits, 85 has always been a ripe old age for human beings.
Emphasis on "old."
Advances in medicine and the understanding of genetics are pushing the boundaries of our collective lifespans, but if you read the death notices in the newspaper, you can't help but notice that most people who pass away are still mostly in their 70s and 80s.
And so, as I undertake any sort of long-term planning, I do it now for the first time with the idea that I can only look so far ahead.
Barring acute illness or accident, I'm nowhere near the point of shuffling off this mortal coil, of course. But you do start to realize that we all have an expiration date. And it's coming sooner or later, no matter how hard we try and stave it off.
It's not like I'm constantly thinking about death. It's just occasional, though I imagine it gets a little more frequent as you get into your 60s, 70s and beyond.
I could very well still be kicking until I'm 100 or more. Can't say for sure. But any longer-range goals I set for myself these days tend to be within a shorter time window than they used to be.
Say, for example, "I want to still be living next Thursday."
That feels pretty manageable.
