Simultaneous solution of the solar neutrino and pulsation problems strongly suggests that in the center of the Sun, energy is transported by a more efficient means than is provided by current, conventional physics. Here, in a first, isothermal approximation, the main-sequence consequences are explored of supposing that the Sun and other 1 solar mass stars contain a relatively efficient means of central energy transport. It is found that, for given initial compositions, the ages of models reaching a given turn-off surface temperature may easily be reduced from the conventionally deduced values by 15-20 percent. The models leave the vicinity of the zero-age main sequence with central hydrogen much less exhausted than usual. This indicates that the possession of a near-isothermal core and the attempted violation of the Schoenberg-Chandrasekhar theorem dominate over mere hydrogen exhaustion in determining the time for departure from the main sequence. Areas of astrophysics that may be affected by these results are indicated.
