Esse é o oitavo post sobre o livro Plano B preparado pelo autor. No final dele estão os links para os detalhes do livro no site, ou então para os sites de venda das livrarias. Aproveite tudo o que o John tem a dizer, qualquer dúvida, cheque no site dele: www.thackara.com , ou aguarde até novembro quando estará no Brasil:
Imagine, for a moment, that you are a penguin. You hang around on ice flows, in extreme cold, for weeks on end. Standing there, in bare feet, you are able to sustain a temperature differential between your own body and the outside environment of eighty degrees Celsius. Every now and again, when you’re feeling hungry, you jump into the icy water, catch a fish, and then clamber back onto a sunny beach. You do this without ever over- or underheating. The secret behind this impressive thermal performance lies in your dense feathers: When a nasty wind gets up, they reduce airflow around your body so that it slows down and warms up, like the water inside a wetsuit. Your feet are also remarkable: They open like a fan to get rid of excess heat when you land from a flight—then, back on the ice, they act like radiators and heat up the ground where you’re standing.
