People often ask me what my worst age marker is; my left ear is 64 years old from hearing damage.

I've been trying to rebuild my hearing. I have hearing loss from shooting guns as a child and also having music too loud. These are Skullcandy headphones and I use this for audio cardio. So this ear is aged 64 between the ranges, 4,000 hertz and 12,000 hertz. I'm basically deaf. I use these every day and do 60 minutes of stimulation in those frequencies. And there's some evidence that this is helpful to people. We have yet to see a benefit. We're still early on.
