Okay.
Dr. Rai, I was speaking to a previous witness with regard to the battery life for e-cigarettes. I used my son as an example. He's in the military and likes his e-cigarette, but when he goes on an exercise for six to eight weeks, he's kind of hooped, so he takes his four or five cartons of cigarettes along with him because he knows the battery will be running out.
Through your company or any others that you're aware of, can you provide us details on potential battery life? Are there ways of recharging that battery for those who are in remote areas?
