Initially I assumed this would increase average lifespan by 25% or so. But it doesn't. Like if you assume zero percent chance of dying before age 80 and 10% every year after, then your average lifespan is around 85 years. If you eat chilis then it doesn't affect your first 80 years at all and only gives you an extra year or two after 80, so maybe 87 on average. Obviously this is a simplification but shows that eating chilis won't automatically make you live to 125. (Assuming the headline holds, which...)
