Anyone else have no concept of age or time

I have a problem with age. Time is fluid to me and doesn't mean much to me. I dont feel any different now then I did in my teens. I did stop growing emotionally at about 19. I have pretty much stayed the same personality wise for decades. I dont understand how people are supposed to act. Ive come to accept this and am thankful that I'm at least at 19 emotionally.
