Well being the kind of guy who dances anything, anywhere with anyone. . . . . .there are general patterns that apply to all kinds of dance. If you want a dance stand up a position yourself at the exit of the dance floor at the end of a dance and seek eye contact with someone coming off the floor. If you are seated, get a seat near one of the exits and do the same. Anyone standing up looking at the floor is looking for a dance. Make eye contact and you're on. Similar if they are looking intently into the floor sitting down If you are guy, try and sit apart from a social group - ladies will make eye contact or even walk right up to you. The age thing - well we all want to dance with skilled attractive young dancers. . . . . but that is not much of an issue once folks assess you ability level. If you are completely new to a venue, do a little display on the walk to the bar, or at the bar, feather step or a sort of slow gancho as if you are scratching yourself (I've done that outside of dance setting (boredom) and picked up people for dancing, usually waiting at airport or railway platform, women zero in on you from a 1,000 yards. 'you're a dancer') . Old people (and I'm old) who dance are either very good or very bad, not so much with technique as with balance, timing and rhythm. There doesn't seem to be much in between. It's that much more difficult to pick up basic skills when you are older, on the flip side your partner might have been dancing for 40 years + in which case you'll the silkyest smoothest dance ever. I'm an old guy and can fairly bounce about the floor in various forms of dance - I get far more than my fair share of young, and even very young (teenagers) partners. I think that's because I'm nice to dance with and got past the stage of wanting to get their knickers off. (though sometimes the thought does go there). I'm there for dancing not anything else.
