You hold grudges

All that pent-up bitterness and frustration could deduct years from your life! “There is an enormous physical burden to being hurt and disappointed,” Karen Swartz, M.D., director of clinical and educational programs at the Johns Hopkins Mood Disorders Center said in a statement. In fact, one study found that people who only forgive when others apologise first or promise not to do the transgression again are more likely to die earlier than people who are less likely to forgive under such conditions. Plus, holding onto a grudge can also increase your blood pressure and heart rate and even lead to feelings of depression. In the words of Elsa from Disney’s Frozen, “let it go.” Your mind and body will thank you!
You love to barbecue

Barbecues are a way of life in many Western societies, but the National Cancer Institute (NCI) says that grilled meats may increase your risk for cancer. Any meat cooked over an open flame at high temperatures exceeding 148 degrees or cooked for long periods of time is exposed to cancer-causing chemicals known as heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs). Apparently, these compounds have been found to change your DNA, which may raise your cancer risk. The NCI recommends avoiding direct exposure of meat to an open flame, cooking meat in a microwave prior to grilling to reduce the exposure time, or continuously turning the meat over a high heat source to reduce HCA and PAH formation.
You always blast the volume on your headphones

If you take your headphones off and hear a ringing or buzzing in your ears, your music is too loud. Even if your hearing quickly returns to normal, you may be doing lasting damage to your ears, says M. Charles Liberman, PhD, director of the Eaton-Peabody Laboratories at Massachusetts Eye and Ear told TIME. Long or repeated exposure to sounds at or above 85 decibels can cause hearing loss, according to the National Institute on Deafness and Other Communication Disorders (NIDCD). For example, an MP3 player at maximum volume can reach 105 decibels or noise from heavy city traffic is 85 decibels. The problem with noise-induced hearing loss is that it’s typically gradual and you may not notice it until it’s too late when it’s more pronounced. The NIDCD suggests avoiding noises that are too loud, too close, or last too long. Head here to find out more in our guide to avoiding hearing loss.
