Why is radioactive decay so rare?

Main Question or Discussion Point

Hi all, I'm just curious about the weak force and how it works.
If quarks and electrons both have weak iso-spin and are constantly whizzing about next to their neighbour's (especially so inside a nucleon), what prevents say, the up quarks from emitting a W- boson everytime they are near a down quark?
Thank you!

A W-boson is quite heavy and can be created only when a lot of energy is available.
