"Fear is the mind killer. Fear is the little death..." - Herbert (Frank not George)

You don't need to be Pollyanna, but most of the people in this world would like to like you - given the opportunity. Predators in cities choose their prey (when hunting casually) by the scent of fear, the rigid walk, the averted eyes, etc.

Any predators in the wilderness (mountain lions, humans, etc.) will choose their prey the same way. So, smile and enjoy everyone you meet - the easiest way to disarm is charm (just made that up, but it is snappy!!). Anyway, if you're on the path, you're more likely to meet (and need) an osteopath than a psychopath.
