I found this short story of sharing on social media.. worth readin!

There once was a farmer who grew award winning corn.

Each year he entered his corn in the state fair where it won a blue ribbon. 

One year a newspaper reporter interviewed him and learned something 
interesting about how he grew it. The reporter discovered that the farmer 
shared his seed corn with his neighbors. 

"How can you afford to share your best seed corn with your neighbors when 
they are entering corn in competition with yours each year?" the reporter 
asked. 

"Why sir," said the farmer, "didn't you know? The wind picks up pollen from 
the ripening corn and swirls it from field to field. If my neighbors grow 
inferior corn, cross-pollination will steadily degrade the quality of my 
corn. If I am to grow good corn, I must help my neighbors grow good corn."
