Is "over forty" the new "under thirty"? 

This is Sandra Tsing Loh with the Loh Down on Science, saying yes!  If you exercise regularly!  (There's always a catch, isn't there?)

French health researchers say it’s never too late to start seeing the cardiac benefits of exercise.

David Matelot and colleagues studied healthy men between the ages of 55 and 70.  Ten had never exercised more than two hours a week.  Thirty had been exercising regularly for years.  Ooh la la!  But while some of these had begun working out before hitting 30, the others started after 40.  

The researchers tested each man's oxygen intake and heart rate during and after exercising, then checked their arteries via echocardiogram.  They found that oxygen use, heart rates, and arteries were healthier in all the men who worked out regularly.  And this was no matter when they started.  It was the non-exercise group that had the unhealthier stats.

So endurance training is good for men's hearts at all ages. 

French men, anyway.  As for French women?  They don't get fat, and that's something.
