How to whiten teeth with hydrogen peroxide
Brush with a whitening toothpaste.
Purchase a whitening toothpaste with hydrogen peroxide at your local pharmacy or grocery store. Brush with the product at least twice daily for at least one month to see results.
OPTIONS:
- Spot test your whitening toothpaste. Look for ingredients that may be too whitening for your mouth or gums.
- Be sure to brush according to the packaging, in order to avoid any irritation. It is important to see the whitening side of the toothpaste (the area that contains the whitening solution), in order to make sure that it is effective.
- Do not brush more than twice a day for the first two months to see results. After three months, a pea-sized amount will be enough to achieve whitening.
- Buy a product with at least 3.5% hydrogen peroxide, which is the standard amount. Be aware that the more hydrogen peroxide in a product, the likely it is to make your teeth sensitive.

answer: Buy a product with at least 3.5% hydrogen peroxide, which is the standard amount. Be aware that the more hydrogen peroxide in a product, the likely it is to make your teeth sensitive.

How to take care of baby carp
Get a 100-gallon tank.
You can purchase a fish tank at the pet store or online or you can use an outdoor pond to create your spawning pool. The larger the tank, the more room the carp will have to move around.
OPTIONS:
- Use plenty of water to accommodate the size of your pond. Try to avoid overfill because carp thrive in moist environments, and overwater can cause dehydration.
- An ideal tank for carp is 8x6 ft (2.43x1.82 m) and at least two feet (60.96 cm) deep. Get a tank made of non-toxic materials to promote carp propagation.
- You can aquarium the tank, or wait to add a fish until it's six weeks old. If you chose an outdoor pond, then it's a good idea to get a 10-gallon tank because it'll be much easier to reuse when your child is grown.
- If possible, keep the water slightly warmer since this will make it easier for them to move around inside and avoid as much water loss. Advertise your new spawning space.

answer: An ideal tank for carp is 8x6 ft (2.43x1.82 m) and at least two feet (60.96 cm) deep. Get a tank made of non-toxic materials to promote carp propagation.

How to survive an early work schedule
Avoid the snooze button.
Many people crave the extra 6 to 8 minutes of sleep provided by the snooze button. However, hitting the snooze button will actually make you feel more tired.
OPTIONS:
- Hitting the snooze button of your smart phone at 9 a.m. means you'll be surprised at the amount of snoozing your body can realistically do.
- When you hit snooze, you immediately go into an early sleep stage. Being interpreted early in the sleep cycle causes you to become more groggy and tired than you would have been without those extra minutes.
- Keep a list of the reasons why you may want to turn off your alarm when you get to work on a certain day. One person might tell you you should just hang out and take a nap.
- Only try this if you can go to sleep and feel rested too within the hour before school or work. Get up early and go do something fun.

answer:
When you hit snooze, you immediately go into an early sleep stage. Being interpreted early in the sleep cycle causes you to become more groggy and tired than you would have been without those extra minutes.
