At 25 I feel much younger than at 21. I kinda don't even know what happened 22-24. I remember being very early in my 20s and thinking on how long it will be till I'm mid 20s and it felt like a couple of days ago, and now I'm 25. My time perception is very weird and has always been though. Sometimes a week feels like a year. I never know what day of the week or date it is unless forced to, and then I quickly forget. If I was allowed to work 6 hours a day, my time perception would be much slower. I'm losing my life to work. :(
