"It makes sense that a year feels much longer when we're 10 (a year ago was 10% of our life) than 100 (a year ago was 1% of our life)."

Well, thats how this calculator sees it..

There are many factors affecting how your life speeds up and slows down. Below you can find a short list of some of the reason why your life may seem to be accelerating as well as some things you can do to slow it down a bit

Why our perception of time speeds up:

Repetitive Events: As we repeat things in our life those events take shortcuts in our neural pathways, this will not make as much of a lasting on us as a new experience would.

Biological Clock: The leading theory on how our brain tells time is that the dopamine system and several parts of the brain work in concert to mark packets or waves of experience. However as we age our dopaminergic levels decrease and thus our biological clocks slow down, thus giving us the impression that the real world clocks are moving faster.

Mental Illnesses: several mental illnesses can distort a person abbility to judge time. Schizophrenics can have the impresion that time distorts, speeds up and repeats. On the other hand, ADHD and clinically depressed people report that time has slowed down.

How to slow down our perception of time:

Reduce Stress: being worried that you can't get everything done in a day will make it seem like time is passing by too quickly. If you can reduce your stress with meditation, listening to music, yoga or other relaxation techniques this will help stretch out your days. Good food, sleep and exercise can also help with stress relief.

New experiences: Having new experiences can create novel memories, these will leave a stronger impression that repeating memories and will give you the impression that you have done more, thus slowing down your perception of time. trying new activities, meeting new people, visiting new places and learning new skills are some great ways to add new experiences to life.
