I feel like such an old man, but I'm 46.

You purposefully let yourself slip. I'm 41. I listen to new music, I understand kid's clothing styles (I was not that different in the 90s), I've kept up with modern technology, I kept moving (due to my labor intensive job), and I've eaten well. That's all on you bro. Old does not have to mean outdated.

Edit: reminds me of my Dad who pretty much stopped listening to any music produced after 1982 and has his garage radio permanently set to classic rock. I made a promise to myself a long time ago that I will never stagnate like that.

Haha, I'm so old that box would contain a typewriter.

Anyway young people like to think they have some control over ageing, like they can be thirty forever. Sorry to say it's not going to happen. There's things you can do to stave it off, but it will catch up with you. When you're young you don't think about it, you take it for granted. When you get old and feel the loss you think about it a lot.

Age caught up with me noticeably at an age older than forty something, but I'm really feeling it now. Forties are young enough where a health regiment of some kind can improve sense of well being. If overweight just getting down to an ideal can help greatly. I've had to battle my weight most of my life and when I can maintain a good weight it makes a really big difference in how I feel.

As far as not getting modern culture, it goes ten feet over my head now. I wish I could live in the the 90's forever.

I have back problems, high cholesterol, high blood pressure

As someone who waited way, way, way too long too lose weight, let me recommend that you review your situation with a doctor.

I've lost significant weight in my 50s and it's completely turned my health around. Cholesterol, blood pressure, blood sugar, almost every indicator was dangerously of whack. I was on a boatload of medications, it was doing jack squat.

Now I get tested and everything is where it's supposed to be. I'm down to small maintenance doses for blood pressure and triglycerides, and I'm off the diabetes medical entirely.

I don't know if weight it a problem for you, but if it is: you can get it under control.

Dude, I remember when there was no electricity at homes, I shit you not.

I'm in my 50s and have started seeing eqpt that I was still using some years after starting work in museums now.

I can now sympathise with my dad who used to be the same with agricultural museums and steam rallies back in the day.

I feel several comments here have already covered how you can change, but I want to give you something different.

It's ok to be "old", you don't need to understand the youth of today, or even like anything they do. Just don't yell at them, or look down on them for doing it.

Live and let live.

Some of my friends went to one room school houses.

On the bright side this post is making me feel really young. So you've got that going for you!

I remember going to a video game museum in Berlin and seeing Game Boys behind glass. (Insert Saving Private Ryan Matt Damon getting old gif here)

It’s sometimes odd to realise that what I consider to be retro (retrogaming is one of my hobbies) was once cutting edge. This post makes me feel weird emotions.

I took my daughter to the Manchester Science Museum, and saw a BBC there. That was my first home computer in '86. I'm 42...

Of course, I still move reasonably well, the tablets keep the depression at bay, the inhalers keep the asthma away and the powerballs keep the RSI away :P My brain is still sharp (And I hope it stays that way as I'm a coder, so I kinda need it), and the glasses keep my eyesight up-to-scratch. Let's hear it for pharmaceutical or physical solutions to intractible issues ;) I also keep up with modern music. Like some of it, don't like others - but then, that's the same as when I was a kid or a teenager. I fight to keep an open mindset, and not slip into the 'rose coloured glasses' fallacy... Having a young daughter is a help to this, because she views everything as new, and interesting, and may I never, ever shutter that desire to learn more. I always try to answer her questions if I can...

This reminds me of the Apple 2 c that was my family's gaming system. My older siblings got interested in computers for games about the time Apple //C computers went for cheap at garage sales, with stacks and stacks of games and tutorials on actually flexible floppy disks. So that was my introduction to computer games.

Same same. Wait until you start seeing Gameboys in history museums.

Come on kid. You're still pretty young! I'm 58 and aside from the damn arthritis and multiple surgeries with my wrists and hands, I'm okay. Like @[email protected], mine would have also been a typewriter in that case. I love tech and try to keep up as best I can. I absolutely love music and try keep up and am always seeking new and undiscovered music in the genres that I love which spans so many genres.

For getting older, we just got to take care of ourselves as best we can. Eat not terribly, get a bit of exercise. Even if it's just taking care of the yard or walking the dog. Take your meds if you have them. Please do this part. I lost a really good friend at 52 because he didn't take his high blood pressure medication.

Ha, a computer in grade school? You young pup! When I was in high school we were writing programs using punch cards you had to feed into a reader!
