  Recent advances in differential topology single out four-dimensions as being
special, allowing for vast varieties of exotic smoothness (differential)
structures, distinguished by their handlebody decompositions, even as the
coarser algebraic topology is fixed. Should the spacetime we reside in takes up
one of the more exotic choices, and there is no obvious reason why it
shouldn't, apparent pathologies would inevitably plague calculus-based physical
theories assuming the standard vanilla structure, due to the non-existence of a
diffeomorphism and the consequent lack of a suitable portal through which to
transfer the complete information regarding the exotic physical dynamics into
the vanilla theories. An obvious plausible consequence of this deficiency would
be the uncertainty permeating our attempted description of the microscopic
world. We tentatively argue here, that a re-inspection of the key ingredients
of the phenomenological particle models, from the perspective of exotica, could
possibly yield interesting insights. Our short and rudimentary discussion is
qualitative and speculative, consisting merely of conjectures, because the
necessary mathematical tools have only just began to be developed.
