I perceive time differently from other lifeforms. For example, when I was 7 years old I thought it would take forever to reach 10 years old. Nowadays, at 65, the years go by like months or days. If I’m busy, having fun, the day goes by faster by my estimation, and if my day is miserable it seems the day lasts forever. Sometimes I wish it could be the other way around!

Some lifeforms on Earth last only a few minutes and perceive time, if they perceive time at all, as a whole lifetime. My pets live 10–20 years, but that’s their entire lifespan. I, however, have had quite a few dogs, cats, even a parrot in my lifetime.

I imagine the same is true for critters on other planets.
