How many ball bearings is too many ball bearings to conceal
in your pockets?
Under normal operating conditions a baker’s dozen can easily
be accommodated in a brace of trouser pockets.
But should a stray ball bearing cause a loss of verticality
and you go tumbling to the floor, the consequence of your body weight bearing
down on 13 stainless steel ball bearings with quite some force will certainly
leave you regretting your choice of contraband to smuggle through customs at
the Portuguese border.
I, for one, are unaware of any restrictions regarding the
import of ball bearings into Portugal which makes the whole endeavour somewhat
foolhardy.
