As MellowWheat said, people don't become conservative as they get older. That's a myth. People just stop accepting new ideas and stop thinking they can be wrong. They stop changing basically. They get what they wanted, but once they do they don't want more so they end up just wanting to keep things the way they got them.

Also, even this I don't think is fully true. The boomers and the next generation or two mostly became conservative when they got older, but I don't know if this is necessarily the rule. They were just raised to be selfish. I've seen it with my parents. They just tend to think about themselves and their family first, and things happened to work out because the economy grew with them so almost everyone had enough, but that's not the case anymore. We need more cooperation if we're going to survive.
