The quasi-particle excitations of a ferromagnet, near a quantum critical point are examined. The weak ferromagnetic state is described by the Hubbard model. The effects of emission of absorption of Goldstone modes on the quasiparticles is examined, as are the effects of the incoherent spin-flip exci
