Curiously, I wonder if there comes a time when you STOP feeling old (at least for a little while).
I recall a feeling of 'getting older' when my responsibilities increased... starting a job, buying a house and being entirely self-sufficient... dramatic changes for sure, and in the aftermath of that you realise that you are not a teen anymore and life is getting away from you.
However, I'm 37 now, and I don't feel like I have aged (much) in the last 15 years. I wonder if it's because circumstances haven't changed much... Physically, I still have all of my hair, it's not greying, I have not gained weight and I don't feel sore or slower. Mentally, I still play games, listen to heavy metal, and regularly stay up until beyond midnight. Me and my wife don't have kids, that might also help.
So I'm at a comfortable spot at the moment and I don't feel old at all. I hope all those in their 20's who are feeling old get to the same happy place soon
