When I was in college, two of the women with whom I became friends were suicides. Neither of them was happy, but I would never have guessed either of them was suicidal.

One of them was just 19 when she killed herself. The other was 21.

I have never assumed “everything is fine” for anyone. Even when you ask, you will only know what you are told and that is rarely the whole truth. People are secretive about their deepest fears and thoughts.

“How are you?”

“Everything is fine.”

“You don’t sound fine.”

“No, really. I’m fine.”

How many times do you ask before you realize you aren’t going to find out anything more? When people mention that aging makes them “think about mortality” I realize I began thinking about mortality when Karin died and then again when Anna jumped. Also when a young couple, just married, crashed their car into a truck and died on the highway.

Yet again, when my first husband got kidney cancer at 34 and lived, but still died young of heart disease and medical errors. Then my brother died of pancreatic cancer at 61. One of Garry’s colleagues — in her early 40s — died while waiting for a bus in Cambridge. When my first husband’s father died of his second heart attack at 52, I was pregnant and sorry he never met his grandson. For that matter, Jeff died at 53 and never met his granddaughter.

I knew a young person who died of a heart attack before age 21. Another internet friend, Rosa, died a month ago of a heart attack. I only found out yesterday when her mother called. She wasn’t yet 35.

And of course, there are all the friends our age who are battling cancer, dementia, heart conditions, not to mention the ones who have “beaten” cancer, but of course, you never really beat cancer. You are remitted and that will have to do.

When people complain about not being as active as they were when they were many years younger, I think they are missing the point. Age will have its way. How it hits you is partly a matter of how you used your body and your personal DNA. Depending on your constitution, your ability to walk, run, ride, or whatever you do may be compromised. Even eliminated.

But then again … are you breathing on your own? Do you get out of bed in the morning, even if it is a struggle? Do you find joy in your life? Do you laugh? Are there people you love who love you too? Is life interesting? Are you still curious to know what’s going to happen?

If any of these things are true, yay for you. You are alive.

Mortality is always with us, whether we are old or young. We may not be paying attention to it, or we may be under some delusion that we are exempt from “the end” because we exercise and eat right. But there will be an end.

Maybe, as Jeff used it say, it’ll be a runaway beer truck. Or something unexpectedly medical. It may be tomorrow or in 60 years. Whatever time you have, be gracious and grateful. Many people don’t get a life full of years. Others get the years and manage to be miserable through all of it.

Enjoy your years, however many you have.
