[obxqhvtm] Contagious handrails

Should you hold the handrails of public stairs or an escalator?  On one hand (no pun intended), you are touching the thing everyone before you touched, so exposing yourself to everything contagious those people had.  On the other hand, stairs are some of the most vicious killers out there due to slips and falls.  Even a light maiming by stairs can leave you injured for life.

The problem is somewhat game theoretic. The degree to which handrails are coated with contagious disease depends on how much everyone else touches it.  The degree to which everyone else touches it depends on what they believe to be the contagiousness of the handrail.
