Known for building skate parks and shaping the skateboarding scene in New York, Andy Kessler, 48, died this week after an allergic reaction to an insect sting, friends and family told news media. Kessler’s death is a reminder that stings can be deadly for those with an allergy to certain insects, the American Academy of Allergy, Asthma & Immunology said Friday. At least 40 people in the United States die each year as the result of insect stings, the academy said.
