Health Concerns

What's up with people these days? Do we have no regard for our health at all?

Example 1:
I am sitting near the front of a bus (Calgary Transit), yet I can clearly hear the music from someone's headphones near the back of the bus. Like, what's the point of blasting your eardrums to nothing? To block out ambient noise? Well now the problem is that you're creating more noise, and people have to block THAT out. So why not just turn it down to a level where you can hear people talking? At least that way you'll still be able to 20 years from now.
That also brings to light the fact that hearing-aid companies are going to do very well soon. Time to invest I guess.

More to come later...
