Does your metabolism slow when you hit 30?

I'm a 22-year-old woman. Many of my friends in their late 20s and early 30s (and older) have been warning me about an inevitable metabolism slow-down and subsequent weight gain around my 30th birthday. They say, "You just wait. When I was your age, I sat around all day eating pizza and I never gained a pound. Now I can't lose weight no matter what I do."

I am sure there's some truth to this, but I DON'T sit around eating pizza all day. I run three to four times a week and eat very healthfully. Will these habits ease the slowing down of my metabolism? Or should I expect some weight gain no matter what I do (as they say will happen)?


Is it better to spread out or binge alcohol consumption?

I am a healthy, fit, 18-year-old male. I have tried both ways: consuming small amounts of alcohol regularly (one standard drink a day) and consuming a lot of alcohol irregularly (10 to 20 standard drinks in one night, but only two days a month, or thereabouts).

I have tended towards drinking a lot irregularly because I have found that I can't notice any effects until I have had at least four or five drinks, 80 to 100 proof shots, usually mixed with soft drink.

I was wondering if either way was less healthy or more of a risk as the same amount of alcohol is ultimately consumed. Also, I noticed that I got a bit more of a 'beer gut' when I had one-a-day than 15 at once; is that likely or just my imagination?


How can I prevent and relieve neck pain?

When I worry/stress out, I find the muscles on one side of my neck (usually the right side) begin to tighten up to the point of acute pain. On occasion, the pain reaches from the back of my ear, down my neck (the most painful point), through my shoulder, down the arm, and in extreme cases to the tips of my fingers. Two questions:

1. How do I stop this?
2. How do I relieve the pain when it occurs?

I'm currently suffering from one of these neck aches, and can't turn my head, so I'd really appreciate your response.
