Was this 70 year-old man flirting with me?

I want to know if he was just being nice and happy to be in a young woman's presence, or if he was "trying" something? I don't have a problem with him but I should know.

I noticed: he was very lively and animated when seeing me, he seemed happy. He went out of his way to help me with some things professionally and seemed impressed with my current project. He also boasted about his past projects and seemed very happy when I showed interest in them. Kind of boasted about it and tried to be a bit macho in that moment. Noticed that in his body language and "preening behaviour".

He laughed quite a lot and for longer than necessary, he also made me laugh on purpose a few times and used "youth slang" in a funny way. He doesn't smile that often so this stood out to me. There was intense and unwavering eye contact. Several times, he stood quite close to me. A few times he was almost touching my hand with his.

In general, he was very kind, empathetic, patient, fun and asked several questions. I guess he finds me an interesting person. When someone else tried to butt in, he didn't let them. He mentioned me being a woman a few times but not in a creepy way. I was surprised by all this because he seems rather closed off with people, but I guess with the ones he likes, he's nice. I just wasn't expecting him to be so animated.

When we said goodbye, he seemed to make it clear that we can meet up again professionally, which I hadn't expected as that would actually be a big help.

I'm 28 and he's at least 70, do men of this age flirt as a means of communication or are there some who actually try to get somewhere with it? This has never happened to me before so I'm not sure if these are his "fatherly" feelings towards me, though I don't have the feeling he views me as a child.
