The first REAL sign you're getting old is when you're in your late 20s, and realize you can't go out all night, drink whatever you want, and spring out of bed the next morning with clear eyes, ready to take on the world.
And according to a new study out of England, the age when people suffer the WORST hangovers is . . . 29.
The theory here is that at age 29, you still drink like you did when you were younger . . . pounding way too much cheap liquor, mixing different types of alcohol, and going for sugary drinks . . . but your body can't handle it anymore.
The study also found the average hangover lasts nine hours and 45 minutes.
And the peak PAIN from a hangover happens at 9:45 A.M., just after you wake up.
