Jumping repeatedly over a moderate obstacle makes their leg muscles and joints stronger: an antifragile behavior. However, jumping from 5 meters tends to instead break their legs: a fragile behavior. It turns out that antifragile entities exhibit antifragile behavior only to a limited range of stressors. If the stressor is extremely high, even an antifragile entity will break. If a stressor is too low (such as lifting a matchbox), no benefit at all will take place. Therefore, antifragility is not unconditional.
