NEW RULE:

Everyone takes off their FitBit / PolarLoop / activity tracker during sex.

(No, not because comparing uploaded data might show simultaneous nookie. Because a FitBit band can scratch a cornea, and a PolarLoop suddenly lighting up red makes it look like you're getting it on with a Cylon.)

There is still that elevated elbow-to-the-head risk when three people are moving around, but at least we can modify SOME variables.

That concludes today's triad-safety PSA.
