Am I the only one that doesn't know my cholesterol levels?

Seriously, I feel like a moron for not knowing something that's so important to my health.
My doctor said I'm "too young", so they're not going to check it... Yet, they can check me for diabetes?

I'm worried for two reasons:
1. My father had it (he died in his 60s)
2. I'm a bit overweight (but I'm working on losing it)

Another thing: I stopped eating fats.
Am I the only one that doesn't know my cholesterol levels?
