Are happy people different from you and me?
Maybe not, but things certainly line up differently for them. Or is it the other way around?
If you deliberately stand up straight, swing your arms, "walk the walk" before you feel the feeling, can you feel your way to an uplift no matter which way the wind blows?
New science says you may be able to forget your troubles, come on get happy, just by doing The Happy Dance. Or the Silly Walk.
Or something akin to hot yoga.
