    So let’s take a look at if you have some damage to these structures and what affect that has on function. So presbycusis is a cumulative effect of aging on hearing. So as we get older, we all know that your hearing tends to go. We all have our parents where they’re like, “What?” and you’re repeating yourselves. Now, you can say, “I understand.” And you don’t have to get mad at them, right? You’re also going to have other types of damages which I’ll highlight in just a sec. So progressive and irreversible bilateral symmetrical age-related sensorineural hearing loss. That’s a mouthful. So what we’re saying is progressive, it’s going to get worst as they get older. It’s irreversible. It’s not something you can fix. Bilateral symmetrical, meaning it’s happening on both ears. Age-related, it’s because our loving parents and grandparents are getting older. And sensorineural means that this is due to a lack or inability of us to detect the sensory information because of damage to these neurons leading to hearing loss. Okay. So I hope all that make sense. You’re also going to have other forms of hearing loss but that’s distinct than this age dependence sort of low and slowed progressive damage I’m talking about. You’re also going to have something called tinnitus. I’m sure you’ve heard that term before as well and I’m sure you’ve experienced it and you have that ringing in the ear. Have you ever had that before where it goes -- and you hear that for a couple of seconds and it goes away? What’s happening there is you’re actually feeling or hearing or experiencing damage to some of your hair cells and that’s also irreversible. So being in times where you’re in loud, loud concerts or somebody is yelling at...
