Everyone saying their health, which isn’t wrong.What’s really going to affect you is your parents' health, presuming they’re still alive and you have a good relationship with them.

If they’re like mine, they’ll be stubborn and won’t acknowledge their weakening faculties. Try getting someone who’s driven for 60 years to surrender their license because their eyes aren’t so good.And when one dies, the other will likely have fallen into a very co-dependent lifestyle, and the structure is completely destroyed.You know it’s going to happen, but you don’t realize how it’ll manifest itself until it plays out.Edit: well, this took off. Glad to hear this actually helped some people. But yeah, it sucks.

I’ve seen way too many people who spent their 20s and 30s grinding. They end up with full bank accounts, but no real friends, community or life experiences. Those are the people who end up with epic mid life crises.Money comes and goes, but genuine friends and experiences can’t be bought.

Like everyone else said - Your health goes downhill after 40. Get active. Enjoy it. Love it.Find out your family’s medical history. In some cases, doesn’t matter what you eat or drink, you’re gonna get nailed with diabetes or heart disease or cancer. Find out if it runs in your family history and prepare/plan for it.Save your money. And if you already are, save even more. Inflation / Cost of living has shown us that a million dollars doesn’t even buy a home here. Doesn’t keep you comfortable for retirement. Save, invest, become financially literate.People will come and go. Don’t get attached or take it personally. We are all on our own journey. Enjoy them when they are with you and be happy for them from afar when they drift away.
