We living in a world ruled by danger...Playing safe is a key....I have got used to reading the environment, looking for key hints all over the place....Most people I believe are safe and if you exposed to a group..yo amplifying your risk. If you know your your playmates and by been observant can pick up alot without knowing.
Ask, be aware, loook for signals and be honest works well. I believe that "Birds of a feather flock together..." Common sense and self preservation will rule so I say each situation will determine what to do and what not to do....
Knowledge in itself will not change behaviour but the power of intuition and a woman has a 6th sense, they must use it wisely...
I am not a wild card, but have met with some amazing people on the site, so far the above has worked...BUT Play safe would still rule as all the medical researches who spend their days in laborarties would tell you so and they should k now..They give you the results
