I don't know, I just never felt the pressure of time past the age of around 17 so I cannot relate anymore. I started to enjoy live significantly more by not worrying about such things.
Interesting. For me and I suspect many others, the relationship goes the other way. Time was of no importance when I was a child, but as an adult it is everything. I have finite time to spend with elderly parents, dying friends, and quickly growing children.
An hour I spend stuck in traffic we're at a airport is a conversation I'll never be able to have with a loved one when they're gone.
