One way I feel old is that I usually hate internet abbreviations and can't understand most of them.

To want the night to end one hour earlier during summer.

Life gets more boring.

A lot of that stuff is to do with stress and if you use body lotions lol.

or if you are asian woman, you could look the same from age 20-50 then suddenly one day wake up looking like a 60year old prune. I seen this happen to some at work lol. It freaked me out. It is like their rejuvenation ability stops rather then gradually slow down and age gracefully.

I've had some "wrinkles" (more like creases or whatever) on my forehead mor like 5 years and I'm 18 lol.

Wow, I must have been old for a long time then.

I’m 41 yet pretty free of wrinkles. Good genes I guess. That said I feel like I’m only getting more attractive the older I get. Actually kinda looking forward to the first grey hairs on the sides, hehe. 

If there’s one thing that I noticed it’s age has nothing to do with how I feel. If anything I’m feeling better with age since I know who I am and what I want and, more importantly, what I don’t want!

Negative thoughts won’t just impact your psychological but also your physical health.

That said, I’m lately thinking about selling my 2-seater sports car (my midlife crisis purchase) because my back hurts when getting out.

Oh, don’t think I’m gonna act like some intellectual filled with wisdom. 

im fine with admitting I’m not. Some people my age still seem to be in the phase where they think they’re hot shit. As young as I am however, I think every age group has a border which separates people who have ‘grown up’ and those who haven’t. For my age group, it’s what I said above. It varies by group, but honestly I think my words still stand. 

I’m not an adult by any means, but I can still see how childish it is to have arguments online (and in general). Does it make someone a child by default? No, of course not

As you grow older again you'll find that sometimes arguments are a thing which needs to happen, sometimes people see a couple having an argument about something and think they're in a bad way... often a couple willing to argue with each other are healthier than those which don't because the ones no longer arguing no longer care that their partner is doing things they see as wrong... they've just grown to expect that and know that if they were to try and argue... it wouldn't change.

No one view is correct in almost any matter, even my above statement puts people who are perfectly happy with their partner in a poor light and is wrong... I've often found myself arguing with me about things I think... and sometimes I come away from those arguments feeling as though I have somehow lost but learned at the same time.

I personally would hate a world where everyone got along and agreed with each other... it would be surreal to me and take away the challenge that is living your life and being unique as a human being.

but hey... I could always be wrong :D
