Walk like you're in a shampoo commercial.
What you do affects how you feel, says author Richard Wiseman, PhD
, in his latest book, The As If Principle
. In other words, behave as if you're happy and you'll be so, scientifically.

Change your walk. Researchers found that people who strode down the street (long steps, arms bouncing) for three minutes felt "significantly happier" than those who shuffled (small steps, slumped shoulders, looking down).
