GIRLS! is this true???

So I was remembering when I used to work at this this popular Liquor/Grocceries store and my buddy the older guy I'll call Bill used to work the register next to mine and we'd talk to each other between customers. Loved this job cause all the college chicks used to come in during the summer half dressed and already drunk. "Oh come on I'm a young guy like I'm not supposed to like that"???Anyway I was a shy guy, but noticed instead of getting in my line they'd get in his and flirt with him???I said one day "what the hell Bill? what do you got that I dont got? I got the looks and hieght and youth on you but why do all this chix flirt with you??? What he said made the most sense to me but I need to know, "Is that true"??? he said the young ones feel comfortable around me cause I'M OLD!!! You your a young wolf and there like this little rabbit ready to get pounced on,any minute and when they see me there like, "he's no threat what is he gonna do"???So in essence the feel comfortable around
