Now we know that the iPod trend brings a spike in noise-induced hearing loss. People set the volumes on their portable music players too high and they wear them too much.
At the same time we learn that visceral fat, fat around internal organs, shows strong links to cardiovascular disease, insulin resistance and other metabolic problems.
It's not just couch potatoes with visceral fat, but those who spend too much time in front of a computer and don't get any exercise.
So get outside and walk everyday WITHOUT your iPod. Movement in silence is what we need more of.
There's a joy in movement and a joy in silence you shouldn't be without for even one day.
