Here's some good news going into a holiday weekend full of red meat and booze . . .



Even if you've REALLY beaten your body up with alcohol, bad food, and smoking over the years . . . it's probably NOT too late to undo it.



Unless you're over 50, in which case you're pretty much screwed.



A new study out of Northwestern University in Chicago has found that you can undo ALL the damage you've done to your body . . . as long as you get rid of your bad habits before you're 50.



The researchers found that if you start to lose some weight, eat healthier, exercise, stop smoking, and cut back on alcohol in your 30s and 40s, your body will recover.



AND you can reduce your risk of having heart attacks and other health issues.
