Good news for coffee drinkers! Research has already suggested that drinking coffee regularly may be tied to a lower risk of diabetes and cardiovascular disease. Now new evidence suggests that it might have an even broader effect, staving off other potential causes of death as well. But when it comes to whether we can conclusively call coffee an elixir for long life … other researchers say that answer still needs to percolate. So if you’re not drinking coffee, it’s probably time to start.
