Wow. I had no idea. Some of these habits, like drinking thru a straw, are ingrained into our culture. BTW, this photo collage is not meant to scare you, just make you aware that some of the choices we make may not kill us, but age us terribly. Read on:

Barring factors outside of our control, the key to living a long life is simple — at first glance. Eat a healthy and balanced diet, exercise regularly, don’t smoke, and get between six and eight hours of sleep each night. But the reality is a lot more complicated.
Repetitive facial movements such as frowning and drinking through a straw have been known to be one of at least 20 mistakes people make that may be aging them. There is so much more we do during the day that affects our longevity. What we do with our bodies has a significant impact on how we feel — and how we look.
The skin is one of the first organs that will show signs of aging — wrinkles, fine lines, dryness, discoloration — but it’s not the only one. Our brain, lungs, eyes, and ears can also be damaged by what we do or don’t do.
Using your phone for everything
Today’s phones are multifunctional devices — they are alarms, computers, navigation systems, calendars, TVs, games, and more. Recent research has shown that 36% of teenagers and 26% of parents wake up to check their mobile devices for something other than the time at least once a night.
Overuse of technology can eventually lead to what is now called “digital dementia.” The term was first used by German neuroscientist Manfred Spitzer in 2012 to describe how being so attached to our mobile devices can result in the breakdown of cognitive abilities similar to people who have suffered a head injury or mental illness, including short-term memory loss.
Applying sunscreen only in the summer
“Although the UV rays may be less intense in the winter, they are always present and pass through clouds,” said Dr. Heather Richmond, a dermatologist at the Dermatology and Laser Surgery Center in Houston.
Damage from UV radiation is cumulative throughout your lifetime and causes gradual photoaging — wrinkles, loss of elasticity, brown spots, and uneven skin tone. “Additionally, UV radiation causes damage to the DNA in our skin cells and may ultimately result in skin cancer,” Richmond said. Daily sunscreen 365 days per year is critical to protect your skin against these changes, she noted.
Wearing a hat instead of sunglasses
Hats are always helpful for protection of the scalp, face, and neck from the sun. “However, sunglasses are recommended as well since, depending on the angle, the eyes or areas around the eyes may not be in consistent shade, depending on which hat is used,” Richmond said. “In addition to protecting against fine lines around the eyes, sunglasses also protect the eye itself from sun damage, which can lead to [vision] changes,” she added.
Rubbing your eyes
No one can argue that rubbing your eyes is not a natural reaction to being tired. It’s almost instinctive and it feels good. However, as is the case with most habits, a problem occurs when it’s chronic. The issue with rubbing your eyes all the time is the sensitivity of the skin around them. It’s one of the places where aging signs first appear. The pressure applied to the skin can break small blood vessels, leading to the formation of dark circles and drooping eyelids.
Taking hot showers
Hot showers, especially in the winter, feel great. But the hot water removes natural oils and moisture from the skin. Dry skin can ultimately result in itchiness, redness, scaling, and can make eczema worse. Dermatologists recommend short showers with lukewarm water.
