I spent a week chatting with people over 80. Here are 4 pieces of wisdom they shared.
"No one warns you how many of your new friends will pass on."

Two hands of different ages grasp one another.
There are only a few things in this life we can't evade. One of them is aging. Sure, there's Botox and facelifts and all that jazz to help us look younger. But in the end, our cells simply insist on keeping score, and no matter how hard some might fight it, our DNA is bombarded with hits that will eventually take us down.
The good news is that with years often comes wisdom. I like to think of our minds as though they were hiking trails. Each trail has a sign, but instead of telling us which way to go, the signs remind us who we are. This past week, I was honored to read some of those signs at the senior home where my mom resides. Nearly every conversation, at least for me, yielded little sage sachets of advice that are truly invaluable.
Know someone before you marry them.
A woman in her early 80s shared that it takes about a year for someone's "true nature" to be revealed, even in the most intimate of relationships. (This, at least according to a professor she had in graduate school.) In other words, she says, "A person can hide their psychological pathologies, on average, for about a year."
So, she wishes younger people would wait at least that long before moving in or getting married. "Slow down," she said. "Really take your time before you take the leap. Everyone puts their best foot forward at first and then sometimes that mask can slip. Don't get stuck."

Some research shows that the "honeymoon phase" can, of course, vary in length. Brides.com shares, "The honeymoon phase is an early part of a couple's relationship where everything seems carefree and happy. It usually lasts from six months to two years and can be marked with lots of laughs, intimacy, and fun dates."
No matter how long that phase lasts, her advice to slow down and really get to know someone before fully committing seems like (mostly) a good idea.
Listen to your doctors

I met a woman who was a retired OBGYN. We talked at length about perimenopause, hormones, and life after 50. She urges, "Do the research, but also (for the most part) listen to your doctors. Most of them know what they're doing."
We both kind of laughed, and then she leaned in and said, "No. Really." She added, "Nothing wrong with getting a second, or even third opinion. But listen and read all you can before it's too late."
Understand that time is precious

One thing my mom rather casually mentioned really stuck with me. This was how difficult it is to make new friends—and not for reasons one might think. Sure, senior living facilities can be just as cliquey as groups were in middle school. But for my mother, it was less about fitting in and more about fearing she would lose people as she grew to love them.
"No one warns you how many of your new friends will pass on. When I first moved here, I befriended a brilliantly funny woman and within six months she was gone. This happens more and more and you never get used to it. You're never prepared."
If you don't want to eat dinner at 4:30, you don't have to.
On a simpler note, this one might be obvious to some, but it was certainly a common topic among the people with whom I spoke. Even though they serve dinner at 5:00 in many senior homes, it doesn't mean you can't put it in Tupperware and save it for later. To that point, just because people age, doesn't mean they have to go to bed at 8:00 p.m. (Though for many, that timeline is just perfect.)
One man noted, "Just because we all live in one place doesn't mean we all become one person. We've got night owls and early birds and every other kind of bird you could imagine. Eat and sleep when you want to. It's still your life."
His friend added, "If you want to play Mahjong at midnight, do it!"
