There's another issue here - and I have some limits as to what I can say - but there's some real question as to the viability of the chemical masks, the protective gear used by our soldiers.

I'd like people to listen to our soldiers. They were there. They heard the alarms go off. They tasted the substance in the air. They spit up blood. They had rashes on their bodies. They got sick.

First off, I'm not a scientist, and I make no apology for that.

The bottom line to this is, there are few doctors who have any expertise in chemical exposure.

I see more people taking charge of their well-being through the use of data and digital sensors, wearable health bands, and smartphone apps that can track and quantify everything from their heart rate, blood pressure, and sleep quality to steps walked and calories consumed.

Even if you have a terminal disease, you don't have to sit down and mope. Enjoy life and challenge the illness that you have.

Yes, you can get addicted to exercise.

When I was 27, I felt old. I didn't feel healthy. I just wasn't taking care of my body, and I had a body that wanted me to take care of it.
