Ever wonder why certain medications are called "wonder drugs"?

Sometimes it’s because of the tremendous health benefits the drug provides for a particular condition, like insulin for type 1 diabetes or antibiotics for pneumonia. Or, it might be because the drug is good for many different conditions: aspirin has often been called a wonder drug because it can relieve pain, treat or prevent cardiovascular disease, and even prevent cancer.

Could metformin be joining this list? It’s approved in the US to treat type 2 diabetes when used with diet and exercise by people ages 10 and older. But in recent years, interest has grown regarding its potential to prevent or treat a variety of other conditions, including aging. Yes, aging. If that’s true, "wonder drug" might be an understatement.
