Time-scales

Yes some day we will be able to screen embryo for optimum gene,,, but the
question is, what is "optimum".

Having "tall" genes may make me a better qualified basketball player than a
small person, strictly because it may be easier for me to dunk the ball in
the basket and slap out someone elses shot.... but does it make me WANT to
play basketball? ENJOY playing basketball?

You know how the grass always seems greener. :-)

I will curse my height because it makes people stare at me, bumps my head on
doorjambs, makes my legs cramp in airline seats, predispose me to heart
circulation problems and more. Or if it was above average intelligence,
because I may not be as satisfied just sitting on a beach, breeding with
free loving wimmin', drinking and eating my fill of easy to reach coconuts
and lobsters and generally being oblivious to the impending doom from a
super nova or giant asteroid that I can't do anything about anyway. I can't
be happy with simple pleasures and feed Ba'al like the old Star Trek
episode. No Eden for me.

Becauseof my membership in my planets intelligencia I need to decide the
best course of action / lifestyle for my people, which means that *I* am the
one that worries about making good decisions, stress and get heart attacks
and strokes because my constant study and focus on mental issues does not
move me to actually exercise my sorry -assed body. :-)

You can't win for losing.

I don't think we have gotten to the point were we really understand enough
to make these kind of culling decisions.

I am reminded of the simple salmon. Omega 3's or fish oil are wonderful for
good health. Salmon becomes popular. To meet the demand, fish farming comes
into play. Artificial pellits are now the feed for the salmon. Omega 3
drops. The bright orange filets are simulated through dyes that are fed to
the fish (otherwise they will appear dull and grey in color, hardly the
appeal we have grown to demand. Now farm raised salmon have no fishoil that
was the reason for eating it in the first place, but now everyone can
afford and get a share.

Blah!
