It’s hard to stay hopeful these days. Stanford professor Jamil Zaki has been studying the incredible depth of human kindness for decades, but even he gives in to cynicism when he doubts our ability to be civil and cooperative.

That’s a shame - because shedding cynicism and grasping hope will make you happier and healthier. Jamil and Dr Laurie Santos look at the scientific evidence showing that we should be more trusting of other people and optimistic about our facility to work together.

Jamil's book Hope for Cynics: The Surprising Science of Human Goodness is out now.

Here's a preview of another podcast you might like: Travel That Matters. This episode features an interview with Marcus Samuelsson, an award-winning chef, restaurateur, cookbook author, philanthropist and food activist.

Marcus shares with us what he eats at ballpark stadiums, where he goes to buy his spices and sauces in LA, and the differences in food and culinary scenes across the continent of Africa. Marcus also shares why food lovers should consider Sweden as a top destination.

Marcus goes on to recount some wonderful stories from his experience in filming with Anthony Bourdain, as well as how filming No Passport Required (PBS) really exposed him to the bounty of food cultures across the U.S. (and what his favorite food cities are now.)

Finally, Marcus talks about the impact one of the country’s most cherished food writers, Jonathon Gold, had on the food scene in Los Angeles and beyond.
