6. Don’t eat popcorn.

Who doesn’t enjoy a large bucket of salty, savoury popcorn while watching a movie? It’s become customary to have some Coke and popcorn and watch a movie. But in reality, it’s a pretty bad habit. The good news is that giving up isn’t that difficult. Popcorn, according to dentists, can harm your teeth. Even with routine cleaning, small pieces of popcorn can get caught between your teeth and be exceedingly difficult to remove. The high fat content of movie theatre popcorn is another factor to take into account. The next time you go to the movies, try skipping the popcorn. You might be shocked to find that a film without it is just as entertaining.
