  Observations of young open clusters show a bimodal distribution of stellar
rotation. Sun-like stars in those clusters group into two main sub-populations
of fast and slow rotators. Beyond an age of about 500 Myrs, the two populations
converge towards a single peak distribution of angular velocities. I argue that
this evolution of stellar rotation in open clusters results from a brief
episode of enhanced angular momentum loss by strong stellar wind during the
early evolution of rapidly rotating Sun-like stars
