What do you know about investing? (UPDATE)

My friend and I were talking at work today about some of the customers we talk to and the things they just don't understand or know about investing. A lot of them seem EXTREMELY naive when it comes to finances and investing and I mean EXTREMELY. But then we thought, is it that they don't know very much, or is that common and we just know more because we work in this field? So, I decided to set up a little poll. I have taken it down now, but here were the results after a couple days:

The question was, "Do you know how an IRA and a mutual fund work and the difference between the two?"

Responses:

Yes, absolutely - 6 votes (23%)
Pretty much - 0 votes (0%)
Eh, Kind of - 5 votes (19%)
A tiny bit - 2 votes (7%)
Not at all - 13 votes (50%)

It really surprised me that 1/2 of the responses were not at all. I guess I just assume that people know something about it, but again, it's because I've been doing this for almost 5 years. I would love to help anyone out that wanted some info on how to start or anything like that, because working in this industry and seeing people who are about to retire and only have like $50,000, makes me really sad. How can you live in your retirement years with only $50,000... you can't. I won't give advice, but it's ridiculously important to start saving something now. That's just my two cents.
