The paper addresses the problem that young stellar associations often show different ages depending on what stellar type is being studied. A pertinent example is the case in which the stars on the main sequence yield one age while the stars still in pre-main sequence contraction yield another. The explanation for this put forward by the author is that magnetic inhibition of convection, preferentially acting on the lower-mass, pre-main sequence stars slows the contraction thus bringing the ages back into agreement.
