OnEaster Sunday in 2014, Christian Angermayer, the German investor, was on the beach on the Caribbean island of Canouan with three friends, contemplating whether he should take magic mushrooms. Before he made his decision, he called a professor he knew who studies psychopharmacology. He explained to Angermayer that he was in the perfect set and setting, was of healthy mind, and he should try it. So Angermayer, who says he feared he would end up freaking out and living as “a farmer in Argentina,” sprinkled some mushrooms in yogurt, ate it, and let the drugs take hold. “I always say that I need to build a huge mushroom statue there,” says Angermayer, now 48 and worth $1.2 billion. “It was the most important positive experience of my life. When I came out [of the trip], although it took me years to get the thesis right, I had the first inclination that if it helped me this much as a happy healthy person, I can see the validation for how it can help people with mental health issues and beyond.” Angermayer spent the next three years working on that thesis. On December 29, 2017, he took another trip, this time he came away with message from the divine: Go forward. There is no downside.By Will Yakowicz,Forbes StaffLearn more about your ad choices.
