Hypochondriac's dream! Or if you have a big family, maybe you could ask enough questions to justify $50/month. But I'm having a hard time picturing relevance to the typical single person or senior, at least one who has an established relationship with a health provider and adequate insurance.
With the rise in deductibles, and still no formal structure for telehealth reimbursement through insurance companies, more people will start sourcing out other options for low cost alternatives. $50/mont isn't for me, or a lot of people, but I wouldn't be so quick to dismiss it, especially on family plans.
