		Many of our daily habits could be sabotaging longevity, according to the 
		thought-provoking book The End of Illness. Here are some of the worst 
		culprits that might harm your health.

		Your unpredictable schedule
 One of our biggest stressors is not finances or marriage but the lack of 
		a regular routine. Even simply eating lunch an hour later than usual can 
		spike levels of the stress hormone cortisol and disrupt your body’s 
		ideal state. Try to eat, sleep, and exercise at the same time every day, 
		365 days a year.

		Your fruit and veggie selections
 
 By the time produce travels from its source to store shelves, it has 
		lost many of its disease-fighting compounds. Buy fresh veggies locally 
		or when in season. If not, stick to frozen, which is prepared at peak 
		ripeness to lock in nutrients.

		Your gym workout
 Even if you exercise vigorously, spending the rest of your day sitting 
		could affect cholesterol, blood sugar, and blood pressure. Find little 
		ways to get moving all day long, including these sneaky ways to stay fit 
		without working out.

		Your nail biting
 Rachata Teyparsit/ShutterstockNail biting is more than just a bad 
		tendency; it can also wreak havoc on your health. In a small Turkish 
		study, 76 percent of nail-biters tested positive for diarrhea- and 
		vomit-causing bacteria like Escherichia coli, compared to just 26.5 
		percent of non-biters.

		| Your "sad desk lunch"
 
 Katarzyna Zdanowska/ShutterstockYour office is a breeding ground for 
		bacteria—and unfortunately, your keyboard is one of the germiest spots. 
		In fact, a 2013 study discovered that in just one day, more than 50 
		percent of surfaces and employees can become infected with a virus. 
		Eating lunch outside (or at least away from your desk!) can reduce how 
		much bacteria you are exposed to on a daily basis.

		Your smoking habit

		to quit this vice, here’s one more: Smoking can decrease your immune 
		function, making you more likely to catch the flu, cold, or pneumonia.

		| Your unwashed bed sheets
 
 Bad news: Dust mites love your warm, dark bed as much as you do. While 
		they are relatively harmless by themselves, their droppings and 
		discarded body fragments can trigger asthma and allergic reactions, 
		according to the Daily Mail.
