Fundamental Particles

[pallidin]

Perhaps this question has been addressed before, but, allow me to ask:

What consitutes the classification of a "fundamental" particle?
Does a fundamental particle have ANY half-life? Seems it would not.
Is a fundamental particle completely impervious to destruction?

Fundamental fermions do not decay, but "transform" one on another.
