Time shift (bible)?

why does time seems to move so fast when you are older? People come and go out of your lives. People die and people is born? This is for all my spirtual people to help me out about time. Example One minute you bustin your *** at work, next you at home getting grub next you arguing with your baby momma next you chillling with your homies next you at school and now you repeating a different process. Moments don't seems like they last long at all.
