Eggs in a basket : too many or too few?

On a continuum of human personality types, there will always be those of us who uncomfortable about the numbers of eggs in the basket - even there are just two eggs, one black and one white, they'd still like them in separate, non touching, baskets.

And there will be others, like Martin Henry Dawson, who feel you can never have too many different eggs in the basket - never have too much diversity in your portfolio or too much biodiversity or too big a gene pool.
