If you really want to understand what science is saying what you actually DO NOT want to do is "Google it." Google is NOT great at returning results that accurately communicate what the scientific findings are about biology, nutrition, social science, psychology, performance enhancement, or anti-aging. What you actually want to do is search PubMed here https://www.ncbi.nlm.nih.gov/pubmed/

I use a swing dance move called a double crossover. Here's how to pull it off... While holding each other's hands, I lift her left hand up behind my head so her hand sits on my right shoulder. She does the same, then we release our hands behind our heads and slide our opposite hands to each other. This fun move takes about 90 seconds to learn and looks great. You can do it dancing to jazz, salsa, hip hop, or even rock.
