Oh, and, BTW, they seem to have a non-zero (negative) "binding"
energy, but we can ignore this for simplification. But conceptually,
it gets subtracted from their total mass in their COG.
By "binding energy", I mean that, conceptually, moving them in
from +oo and -oo, respectively, into the lab "releases" some
energy because one fermion is "falling" within the electric
field of the other fermion. (I did not think of positronium.)
