We emphasize the role of Heavy Fermions in various aspects of fundamental physics such as:
i) Generating all CP violations from a vaccum phase.
ii) Generating Naturally Suppressed Deviations of 3x3 Unitarity
and Flavour-Changing Neutral Currents.
iii) Providing a Possible Solution to the Strong CP problem.
iv ) Impact on CP Asymmetries

We construct extensions of the Standard Model with two Higgs doublets, where there are flavour changing neutral currents both in the quark and leptonic sectors, with their strength fixed by the fermion mixing matrices $V_{CKM}$ and $V_{PMNS}$. These models are an extension to the leptonic sector of the class of models previously considered by Branco, Grimus and Lavoura, for the quark sector....
