We all know that water is tasteless. But it happens from time to time: you pick up the bottle of water you didn't finish yesterday，and it tastes strange. Most often，you tend to drop the bottle in the trash bin，believing that the water has gone bad. But is it true?

According to Time ， of course not，taste has little to do with quality of water.

According to Time ， when water is exposed to the air for 12 hours，carbon dioxide interacts with the H2O in the water，and the pH value lowers slightly. As a result，the water has a different taste.

"But it's most likely safe to drink，" Norwegian expert Truls Krogh told Science Nordic. "If the water is covered and of good quality to start with，in principle it can last a thousand years. That's because when water is fresh，it contains little organic matter. As long as water is held in clean glasses or bottles，no pollutants will enter it to harm our health. "

People in countries like the US，the UK and Australia usually drink tap water. According to

Time ， if tap water is drunk within six months，the chlorine(氯气) in the water will be enough to kill any bacteria and keep it safe to drink.

However，there are also some exceptions. If you accidentally put your fingers into water or store water in unclean containers day after day，microorganism(微生物) will enter the water.

With the help of surrounding temperature，and sunlight streaming through windows，these microorganisms multiple quickly. Sooner or later，the water will be in the charge of the unfriendly bacteria. And if you drink the water too often，then you're more likely to be ill.

And what about water in plastic bottles? Heat and plastic are a bad combination， US researcher Kellogg Schwab stresses. When plastic bottles are used at high temperatures， they produce a chemical called BPA. BPA is something that affects hormones(荷尔蒙) and research has tentatively linked it to "several health damage，including heart disease and cancer"，Time reported.

Schwab suggests replacing disposable(一次性的) plastic bottles with the refillable containers made of metal or glass to deal with BPA.

We sit too much，and researchers are discovering that even working out in a gym several times a week won't necessarily obviate serious problems if we're sitting for the rest of the time. From weight problems to poor blood glucose(葡萄糖) levels，even early death, the message is clear: we need to stop sitting for hours at a time. What to do？" Move more，" say the experts.

So we asked three fitness instructors for their preferred exercises that don' t require equipment and can be done throughout the day at home，in the office，in a hallway，waiting in line at a grocery store or watching TV.

"There are a lot of ways to build activities into a day," says Ottawa­based fitness instructor Christine Dery,  who focuses her classes on core muscle strength and balance. She reminds her students to seek ways to move more outside class，such as getting off the bus or an elevator ride a few stops earlier,  or doing calf raises,  wall squats and wrist stretches while watching TV. " We need to make exercise an important part of our day, " she says." It's about making yourself a priority."

Ben Gervais，a part­time personal trainer and former kung fu instructor in Ottawa，thinks that little moves matter. " Moves like mowing the lawn，doing work around the house, going for a walk with the kids and playing with the kids can all count as activities as long as you get up and move. " He recommends spending the two­minute TV commercial breaks doing wall squats, push­ups and sit­ups, or stepping up and down on a step.

Stott Pilates trainer and instructor Michele Carini says breathing can be an exercise working abdominal(腹部的) muscles and neck and shoulder muscles. Focus on sitting tall and drawing air in, so the rib cage(胸腔) expands like an accordion while the stomach stays tense.

Everyone knows they need to save money. . If you' re often falling short with little money to save and want to turn that situation around，here are ways to get serious about saving.

Pick one or more and watch your savings account balance grow.

Set up auto-draft

Keep saving simple by using your bank's auto­draft(自动提款) feature to schedule regular transfers from your checking account to your savings account. . Before long you'll notice growing numbers in your savings account.

Saving change is far from a new idea，but it works. Make a habit of emptying all of your change into a jar each night. When the jar is full，put the money into your savings account.

Bank your raise

If you are at a much­deserved raise from your boss at work，try your best not to think of it as an opportunity to improve your lifestyle. Instead，think of it as an opportunity to increase your savings. Send that extra amount to your savings account. .

Hide your money

. Keep your savings out of reach by keeping it at a different bank than your checking account. The extra trouble will make you think twice about spending it.
