People say that getting old sucks. In my humble opinion, it's still better than the alternative. Yet each decade comes with its own perks and woes. Interestingly, according to research, the 5th decade of a person's life is the least joyful. You see, a person's happiness correlates to their age: we get a U-shaped curve if we were to look at a person's entire life.

We're happiest when we're little, and we're the least happy in our 40s. Then, after our 5th decade, the happiness starts to rise again. In 2020, Economist David G. Blanchflower concluded that the U-shaped happiness-age curve applies to many places, not just Europe and America. So, it seems to be a universal experience, not just for developed countries.

But what's it like to be in your 40s? Is it really that bad? One netizen wondered exactly this because they asked: "Hey y'all in your 40's: what are the physical changes you start to see in your body once you leave your 30's? What should we expect to experience physiologically as we get into our 4th decade?" As a person entering her 4th decade soon, I'm starting to wonder: should I be afraid?

Ladies, at some point in your late 30s you will wake up and realize everything is b******t and you don’t care what any dude thinks about you, lol. After a youth indoctrinated to seek their approval, you realize it’s all b******t.

Don’t shave your legs and underarms, don’t wear a bra, cut your hair short and dye it blue, get all of the tattoos and piercings you ever wanted. That one dude doesn’t find you attractive? Hahahahaha haha….

That is the biggest and most important physical change you will experience as you age.

So much this. I thought menopause was after 50. It's not. It starts in your 40s and lasts 10 f*****g years! And just to really twist the knife, while I'm learning to manage my new hormonal roller coaster - I have to figure out how to support my teenagers who are on the even scarier roller coaster on the opposite side of fun park.

"The Check Engine Light Came On": 30 Body Changes People Experienced After Hitting 40 Let's see...

I threw my back out and wound up on the sofa for 3 days moving a trowel full of dirt from a bag to a planter.

I developed cataracts in both eyes. Yes, both.

Years of terrible work posture (I assume) led to a bulging disk in my neck.

Washing my face with bar soap if I remember has morphed into a whole multi-product routine more complicated than anything I had as an acne-riddled teen.

There is more gray in my hair than brown.

My right knee can tell when it's going to rain.

I don't really drink anymore because the hangovers last for days and just aren't worth it

Sleeping in a weird position means at least one full day of back/neck/shoulder pain

My periods come every 3 weeks now instead of every 4.

I'm pretty sure I could grow a goatee to rival any teenager's if I stopped my daily search for hairs in places I do not want hairs.

Falling asleep is hard. Staying asleep is hard. Waking up rested is a pipe dream

Every so often, I get to wake up in a pool of my own sweat.

But, I wake up.

I'm at a good place in a career I love.

I care less about what others think with each passing day.

I have found friends and activities that bring me joy.

I agree. I'm 52 and most of this list didn't really impact me until I was late 40s/early 50s. If you don't have any chronic health issue by 40 then you're doing great, enjoy your body and what it can do rather than focusing on how it's different from younger years. You can take this either negatively or positively - its only going to get worse from now on so make the most of it

Agreed, you don't have to do anything strenuous, but make sure you just keep moving, even if its going to a walk every day. I noticed if I don't do anything for a few days I literally feel my body breaking down and I'm only 40 now. I understand now why they say 'if you don't move it, you'll lose it' and unfortunately why people who might have an injury/illness and end up confined to a bed for a long period can sometimes never recover from that.

"The Check Engine Light Came On": 30 Body Changes People Experienced After Hitting 40 If you are married with kids and you are not really out of shape but also not one for the gym, you will pack on the pounds if you are not careful.

I was one of those…woke up in my early 40’s and started hitting the gym and taking better care of myself and of course I thought — why did I wait this long?

So….get off your butt and get going.

Also - as you age you dont put on muscle as easily and you don’t burn fat like you used to. All that stuff you used ot eat and drink without a thought starts sticking to you.

And you are just not as active if you are busy with family and career so you have to mindfully plan to take care of yourself.

Now that Im even older Im so happy I started and have kept going - Im in good health, and good energy, sound mind.

"The Check Engine Light Came On": 30 Body Changes People Experienced After Hitting 40 You realize you're going to die.

We all know it, but once I hit 40, I just *knew*, and what it really means. Things hurt more, yet going on 40 years your tolerance for pain is higher than when you were young. So the pains and aches, and the consistently small medical issues pile up over time and you realize your body is no longer "getting older".

It's deteriorating.

You're in a slow decline and you can feel it. Some days you forget, you may even have times when your body feels much better. Maybe you changed some bad habits, or got new good ones. But those old bad habits left their mark and you'll never recover from it.

We get one life on this world and then it's gone. I'm not a religious person. I wish for anything that I was and I could take comfort in dying, but I can't. It's an absolutely terrifying thought because for me, that's it. Nothingness, forever. For trillions of years, countless universe big bangs, over and over, and it'll just never happen again. And I won't even get to experience a single nanosecond of any of it.

I'll take these crappy pains forever, any day of the week, than the alternative.

Why is nothingness terrifying? You cease to be. No more aches, no more pains, no more stress, no more heartache or regret. You will no longer be aware of "missing" anything. Just like you were unaware of anything that transpired before you were born....and likely the first 2-4 years after. Being dead isn't scary. Dying badly is what's troubling.

I’m 45 now. Going to do a tough mudder run this summer and am training for a couple half marathons in the fall. I’ve never been more energetic, healthy and fit in my entire life. I have some more gray, and the laugh lines are a little deeper. Just don’t stop moving.
