In her David Letterman-inspired 'Top Ten' list of life advice, Steinem argued that laughter occupies a unique position among human emotions. Fear can be forced upon us through threats and violence. Even love can be manufactured through isolation and dependence — the Stockholm Syndrome, she noted, 'happens to men too.' But laughter cannot be coerced. It emerges spontaneously when familiar things combine into something new, which is why it is inherently subversive to any system of control. She cited Einstein, who reportedly had to be careful while shaving because sudden insights would make him laugh and cut himself. Her practical conclusion: 'Do not go anyplace they won't let you laugh. Big, important rule. Including religious places.'
