 It's just like anything that's medical. If you catch it early, it's so much easier to treat. Stage one versus stage four. If you think about being in a hole, would you rather be in a hole when you're in your knee deep or chest deep? And it's about that jump back to normal hearing. And when that hearing process has just atrophied and not being stimulated and used, once you do decide to put a hearing aid on it years, years, years later, those systems can have issues reactivating.
