The heaviness of the glueball mass scale is suggested as the source of the OZI rule at low energy. The J/ψ→ ρπ decay "anomaly" implies the vector glueball O has mass mO ≈ mJ/ψ. Such a heavy mass is supported by other glueball studies. Glueball-meson matrix elements turn out to be not suppressed at all at the 1 GeV scale, and a simple and intuitive picture emerges which is consistent with the Gell-Mann-Okubo mass formula as well as the measured sign of ϕ-ω mixing. The suppression of glueball mediated qiqi \longleftrightarrow qjqj transitions and the cancellation mechanism in two-step meson rescatterings are viewed as related by duality. Extensions to the 2++, 3-- meson sectors, and failure for 0± + mesons are also discussed.
