A study was done a while ago where they placed 60s music into an old retirement home. They replicated the 60s so that the participants believed they were in the 1960s.

I will try to find it and hopefully its online. I read it in a subject I took years ago...pfft can't remember if it was research methods 1 & 2 or something else, but will try to find it and post it.

Anyway, the results were astounding, the people in the old home started to reverse the aging process. Health issues dramatically improved etc.

The results certainly support the time theory.
