In a finding that is sure to have the Natural Resources Defense Council ordering their vassals at Mother Jones to insist we are shills for Big Gel Manicure, we have noted that correlation between gel manicures - used to prevent nail from chipping - and cancer was not good science. It wasn't even good epidemiology.
If two women get cancer and have no family of history of cancer but both had gel manicures, that is not worth claiming they cause cancer - it is simply that cancer can strike anyone, anywhere, at any time.
Gel manicures are not a big enough industry for environmental groups to engage in a shakedown, so they are probably safe from too much financial harm.
