Last night during my family's "family time", as usual we read the bible and one part of last nights reading caught my attention. It said that for God one thousand years is like a day, and a day like a thousand years.

That got me thinking a little about "time", and the "perception of time". Also on the effects of "perception of time" on growth rate of living organisms. For most, if not all, living organisms on our planet, "perception of time" is directly related to the Sun, or more accurately the time of a single complete rotation of the earth with respect to the sun(a day). So if days were shorter or longer, would our life expectancy change? (with all other factors remain controlled). Would we grow up/mature (physically) faster?

I've tried to find material regarding this topic but I cant seem to get any. If anyone has any comments on the topic, or would like to share some knowledge it is most welcome, as well as if anyone could provide some links to good reading material.

Thank you ^^

I think perception of time can influence growth. Chicken in commercial farming grow faster than chicken breed naturally. I was told they make the chicken sleep and wake more by tampering with the light. Some metabolism for growth takes place when we sleep. I hope some people in commercial chiken frming can shed some light here.
