Welcome to

1) Being the smartest doesn't mean you'll be the richest and the most successful - nods anyone?

2) The best product isn't necessary the best seller - Note the QWERTY keyboard design which triumph over the sequential A-Z keyboard design. Why? It's the outcome of an attempt to reduce the typebar clash frequency in the old typewriter design at the time, which is probably inapplicable in today's keyboard design.

As for my most recent personal observations: 

I have a fishtank with two axolotls and two freshwater mussels in it - The axolotl eats like a pig creating a mess with every munch. The mussel's food source comes from the resulting debris. Win-win. 

The mussels will at times migrate across the tank a bit painfully and slowly by limping with their foot muscle, however impressive consider how far they can travel (when they want to).

This however, is not a guarantee that they will be moving closest to the food source which is where the axolotls will be creating the biggest mess no matter how hard they try - they probably did an educated guess of where I normally feed my axolotls. Nice try though, but impossible.

In this case. The livelihoods of my mussels are virtually up to chance no? Likewise of being at the right place at the right time, everytime. 

Both my axolotls and freshwater mussels are extinct/endangered to start with - I played god and have been feeding them really well. The above is merely an amusing observation of the life of a mussel.
