Answer:
<em>preparation/determination</em>
Explanation:
People have made a willingness to make a difference in the preparation / determination process.
This is kind of a stage of research: individuals are now making small changes towards cessation.
We try to collect data about what they need to do to change their behavior (sometimes by reading information that could better their lives).
Although exercise is the best way to do that, there are other ways.
Practice controlled breathing exercises, which are easy to do from the comfort of your home.
One is where you take a few small breaths in and one large breath out. Keep doing this.
Breathing exercises are also relatively easy to find on the internet.
