Happy Birthday, Kenneth H. Cooper! Thanks for keeping us all sweating since your revolutionary 1968 book "Aerobics" made jogging cool and turned millions of couch potatoes into fitness gurus (or at least pretending to be). You've truly given us the perfect excuse to keep buying stylish workout gear we rarely use—even though you insist exercise doesn't count unless we're actually moving.Today, as we celebrate your incredible legacy, we hope you step away from counting heartbeats per minute long enough to indulge in some cake—just don't tell your aerobics fans! Cheers to you for making staying fit sound more fun than sitting down. Here's wishing the father of aerobics eternal good health and many happy jogs ahead!
