Maybe body posture plays a role? Maybe a sense of being physically open and relaxed helps?

Strangers always smile at me and talk to me. People always hold doors for me. Other women often stop to compliment me on something I am wearing such as my boots or hat. In stores people will stop me to ask me if I know where something is located even though I am obviously just another customer.

Recently I was riding buses a lot when my truck was being repaired. Quite often the bus drivers would start up a conversation with me (even though they aren't really supposed to talk to riders) and other riders also talked to me.

This is something that has happened to me since I was in my 20's. Maybe it has something to do with having meditated and practiced yoga since my 20's? I never have a sense that people are unfriendly. People are just people. We all have our problems and concerns. If someone doesn't smile at you they might have something pressing on their mind. It might have nothing to do with you. I am rather quiet and don't go out of my way to be friendly. I don't even smile that much! But people always advance and engage with me. That's why I think body posture must have a lot to do with it.

It's also a fact that after meditating for a while one's eyes begin to soften. A lot of long time meditators have smile lines around their eyes. Think of the Dalai Lama. I think having "soft eyes" is seen as attractive. Or maybe even a soft face because I wear sunglasses a lot and people still engage with me. I have noticed that long time meditators often seem much younger than their real age. All good reasons to meditate!
