I have a question but I don't ever see any ISTps in chat . . . so even though it's a little silly question I'll have to put it here.

Why won't my husband take a daily vitamin? What is the deal? Is this a type-related thing or just a hang-up of his personally? He flat-out refuses no matter how much I ask and he's really funny about it.

He also gets upset if I ask him to wear a helmet when he's riding his bike. But he insists our daughter wear a helmet so he must know that they're necessary.
