<human>: Can you condense the text into a few key points?

So...I've posted before about my boss, who I have a crush on. I work as a cashier at Walmart which is why my boss is nine years younger than me.

He drinks energy drinks nonstop. I feel stupid posting this, because he's not my boyfriend. He's not even my friend. He's just...well, my boss. But I worry about this nasty habit. He drinks them in the morning, during the workday, and at night (a bit of facebook sleuthing clued me in to this). I really don't like him drinking them. I worry about his teeth, and his heart, along with all his other organs. I'm really worried and scared. He's a healthy 21 year old, but those energy drinks, especially the way he just pounds them back all day, day in, day out...I feel like I'm at my wit's end, and the kicker of course is that we're too shy to even talk to each other.

I give him reproachful looks when I see him drinking them. I think he senses that I don't really like him drinking them, because a few days ago he drank one in front of me with a smug look, as if to say I had no right to question him drinking so many energy drinks.

He's complained of headaches. I fear that they may be caused by this.

I'm curious, if he suddenly stopped, would he get cranky, like people giving up cigarettes? I imagine his bloodstream must be 90 percent caffeine by now.

I guess I can't really ask how to get him to stop, since I'm not even his friend and have no right. I guess I need to know how to cope with this anxiety and worry. What else can I do? Maybe I could ask someone he actually talks to to tell him that people died of heart attacks drinking that crap.

He also eats Lunchables, but that's another post for another day (unfortunately).
<bot>: My boss/crush has a bad energy drink habit. I'm worried for his health. Need advice on how to cope with being concerned about it.
