    A minor quibble: your distinction between bosons and fermions should be
    between "luxons", i.e. massless particles travelling at C, and "tardyons",
    i.e. massive particles travelling slower than C.  There are both massive
    and massless bosons, and there may be massive fermions (the rest mass of
    the neutrino is currently being debated).

There sure are massive fermions - electrons, protons, and neutrons, to
name three fairly common ones.
