“The most famous lenders in nature are vampire bats. These bats congregate in the thousands inside caves, and every night fly out to look for prey. When they find a sleeping bird or careless mammal, they make a small incision in its skin, and suck its blood. But not all vampire bats find a victim every night. In order to cope with the uncertainty of their life, the vampires loan blood to each other. A vampire that fails to find prey will come home and ask a more fortunate friend to regurgitate some stolen blood. Vampires remember very well to whom they loaned blood, so at a later date if the friend returns home hungry, he will approach his debtor, who will reciprocate the favour. However, unlike human bankers, vampires never charge interest.”

“When you are joyous, look deep into your heart and you shall find it is only that which has given you sorrow that is giving you joy. When you are sorrowful look again in your heart, and you shall see that in truth you are weeping for that which has been your delight.”
― Kahlil Gibran

“We all want to do something to mitigate the pain of loss or to turn grief into something positive, to find a silver lining in the clouds. But I believe there is real value in just standing there, being still, being sad.”
― John Green

“Survival in that era required superb mental abilities from everyone. When agriculture and industry came along people could increasingly rely on the skills of others for survival, and new ‘niches for imbeciles’ were opened up. You could survive and pass your unremarkable genes to the next generation by working as a water carrier or an assembly-line worker.”
