It would take as many human bodies to make up the sun as there are atoms in each of us. The geometric mean of the mass of a proton and the mass of the sun is 50 kilograms, within a factor of two of the mass of each person here.
Sir Martin Rees in a TED lecture. He suggests that humans have evolved to this scale, an almost beautiful mean between stars and atomic particles, because we must be large enough to permit massive complexity in structure while small enough to experience minimal gravitational effects.
It always makes me feel rather happy to think that everything had to be just so for our world, as we know it, to occur. Rees calls this quality of the universe its biophilia and describes it more here.
