Every second counts. We are only on this earth for a short amount of time, and we get to decide how we want to use that time. And if one thinks that the purpose of life is to leave the world in just a little bit better place than we found it, it's hard to think of anyone who has contributed more than Jane Goodall.
I must admit that any favorable mention of the flying saucers by a scientist amounts to extreme heresy and places the one making the statement in danger of excommunication by the scientific theocracy. Nevertheless, in recent years I have investigated the story of the unidentified flying object (UFO), and I am no longer able to dismiss the idea lightly.
