I do these breathing exercises where if I start to feel stressed I breathe in for -- I start at a high number like eight -- and breathe in for eight counts and breathe out for eight counts, until I feel like I can go down to seven and then to six ... and it really does calm me down.

Getting a dog I would highly recommend for anyone. Animals are great for stress. The morning comes, and you have to take those dogs out. And I feel better because I don't feel guilty.

CNN: What would you like to tell women about heart disease?

Janney: We only get to be here once; why not feel the best you can feel? Start making choices that are going to make a difference in your life and the people's lives around you.

You just have to consciously be aware that we're not going to be here forever. This is not a dress rehearsal. This is it. This is all we have. And if you look down and you can pinch more than an inch, it's time to start taking it seriously.

CNN: You've been called one of the most versatile actors in Hollywood. What haven't you done that you'd still like to do?

Janney: Really? Wow. I just signed up for doing a series for CBS called "Mom." Anna Faris plays my daughter. It's a multicam series, the first time I'll be doing that sort of format where I'm performing in front of a live audience for television. I'm really excited about that.

There are lots of types of roles that I'd like to do that I haven't done yet. I've always said I'd like to play action hero; a really physically demanding film role would be fun.

I want to be challenged, work with great people and find better roles. Like the role that I found in C.J.; I like the women that I play who are inspiring to other women. That makes me feel good about what I do, that it has a lasting impact on the world.

I want to do more Broadway. I want to continue doing film. I want to have this show ("Mom") with Chuck Lorre be a great success.

I just want to keep working, because that's where I'm happy, and I think that's what I'm supposed to do in this lifetime: keep working and keep experiencing and keep healthy and stay alive as long as I can.
