You can spend a lifetime discovering things on the internet. Luckily for me, it took me a short time while browsing through videos for good laughs on YouTube.
As always, life finds a way. Amazing what an incentive will cause someone or thing to do.
The birds wanting to crack nuts with ease and safety had devised an interesting system by using their surroundings
Yet we find other birds who find a better way to adapt with no need to inconvenience themselves with a high cost upon their lives. Everywhere and in everything we find incentives. The bird steals but does not think of it as stealing only for the fact that it has received food. For the birds there is only one incentive, to eat.
We are faced everyday with our own decisions to make facing incentives and it is our job to find the easiest way of obtaining what it is we want. Anything can be done... you just need the right incentives to do it.
