I was this role model for heavy people. But the thing is, I never set out to be a role model at all, and I don't set out to be one now. I won't preach to anyone and tell them how to lose weight. I don't know any better than the next person.
A lot of knowledge in any kind of an organization is what we call task knowledge. These are things that people who have been there a long time understand are important, but they may not know how to talk about them. It's often called the culture of the organization.
