Brotherly advice

The best -- and the only -- life advice ever given to me by my older brother, who died when I was fifteen, was "take good care of your teeth, kiddo," offered as a sincere advice about the one thing you must be sure to do in this life, in his view.
It is perhaps not profound, but on the other hand it is a lot better and more constructive than a lot of the bullshit you may hear from some people. Like "live fast, die young." Or "you can't trust anybody but yourself." Or "don't stick your head above the crowd." Or any of the endless anti-life equations that the older generations will use to try and keep the younger ones from overtaking them, or whatever their subconscious rational may be.
