Well, you have to look at the difference between various ratios. Days and
years are not so far apart. minutes and seconds are not so far apart. Hours
and weeks are further apart, but still relatively close.

Seconds and years are pretty far apart, but well within the rang of being
easy for the average person to percieve the difference.

But when 1 second is compared to something like 1*10^20 seconds, I think
that the differences are getting pretty large, and 1*10^ -20 is getting
pretty close to zero, at least the average person would probably percieve it
as such.

Changing units because it makes calculation "more convenient" introduces
human bias.
