Places on Santana Row (in San Jose) have courtyards with fountains and flowers and people like it. People want their own space to look like that and have that nice, cozy feel.

We sell a lot of fountains and water features. A lot of people like the sound for background noise. People get ponds, pumice waterfalls, fountains - anything with water.

I'm appalled, I can't believe a teacher who's supposed to be a role model would do that, and then we wonder what's wrong with our children today. It's really sad to me.

We don't just teach you the techniques, the punches, the self-defense, we also put them under stress so you're also training when it happens on street. You have that stress response. A lot of times, people will freeze. We try to train them through that. Anything that you can do to stay safe and get away, no matter what it is, hit them, scratch, bite yell, scream, just even one thing may save your life.

Attacks can happen maybe when you're ready and you see it coming, or when you're not ready you don't see it coming.

I think it's very important that they understand the people who were killed.
