  We study the coupling arising via perturbative QCD of zero 4-momentum Higgs
bosons to light quarks inside the nucleon. Qualitative comparison with the
results obtained from one-loop-order low energy theorems for the Higgs-nucleon
interaction suggests the existence of a dynamical light-quark mass which falls
off with momentum. Quantitative comparison leads to an estimate of $\alpha_s$
at very low $q^2$ quite near unity.
