I do drink too much beer- at least several classes a night.
I exercise, watch what I eat, and get a physical every year. I haven't even had a stuffy nose in a year or two.
I'm very healthy, my liver enzymes are good, my cholesterol is low, my blood pressure is 90/50, and my pulse is 65. I don't have any health issues, and I don't take any medications at all, not even aspirin.
I weigh 135 pounds and am a size 4. I'm almost 48 years old, and I can outrun/outlift most 25-year-old women who are too fat and eat junk. I'm pretty lean and slim, and fit.
Life is about choices. I haven't had a doughnut in 25 years, or a Doritos chip. I can't tell you the last time I had bread. So, yes, I'm very concerned about my health. But not because I drink beer.
I'm concerned about every American being unhealthy because obesity is killing our nation, including children who are being diagnosed with diabetes in an unprecedented rate (as are adults). I"m concerned that "school lunches" are absolute crap and that physical education is being cut out of schools. I hate being run over in the store by a young (my age) overweight person who needs to drive a scooter to get through Wal-Mart. Those are my bigger concerns.
You know what, from that perspective, you're right, most of us posting here actually are concerned about our health and intake. I was looking at the question more as "Do you worry that your intake is affecting your health?", but should have thought of it as "Are you concerned about your well-being?"
