Retired lab chimps see the sky for the first time

I think that as a society we under-estimate the enormous gratitude we own these animals. We subject them to our tests to make our lives "better" (among useful things, to test make-up and crap like that). In a way we should be ashamed of ourselves that we're even doing this but I guess humans will always be humans regardless of how great we think we are.

Lived in a lab cage for 50+ years? That's disgraceful.
