Why is bone health important?
Your bones are continuously changing — new bone is made and old bone is broken down. When you're young, your body makes new bone faster than it breaks down old bone, and your bone mass increases. Most people reach their peak bone mass around age 30. After that, bone remodeling continues, but you lose slightly more bone mass than you gain.
How likely you are to develop osteoporosis — a condition that causes bones to become weak and brittle — depends on how much bone mass you attain by the time you reach age 30 and how rapidly you lose it after that. The higher your peak bone mass, the more bone you have "in the bank" and the less likely you are to develop osteoporosis as you age.

Honey
Honey is a sweet, viscid fluid produced by honeybees (Apis melliflera ) from the nectar of flowers. It is generally recognized as safe (GRAS), but there have been numerous reports of certain types of honey produced from the nectar of flowering plants from the genusRhododendron and others that have toxic effects in humans and in animals.
Honey is easily absorbed and utilized by the body. It contains about 70-80% sugar; the rest is water, minerals, and traces of protein, acids, and other substances. Honey has been used by ancient Egyptians, Assyrians, Chinese, Romans, and Greeks as a medicinal remedy for the management of wounds, skin ailments, and various gastrointestinal diseases.

Know the risks of tattoos
Know the risks
Allergic reactions. Tattoo dyes — especially red, green, yellow and blue dyes — can cause allergic skin reactions, such as an itchy rash at the tattoo site. This can occur even years after you get the tattoo.Tattoos breach the skin, which means that skin infections and other complications are possible. Specific risks include:
- Skin infections. A skin infection — which might cause redness, swelling, pain and a pus-like drainage — is possible after tattooing.
- Other skin problems. Sometimes bumps called granulomas form around tattoo ink. Tattooing can also lead to keloids — raised areas caused by an overgrowth of scar tissue.
- Bloodborne diseases. If the equipment used to create your tattoo is contaminated with infected blood, you can contract various bloodborne diseases — including tetanus, hepatitis B and hepatitis C.
- MRI complications. Rarely, tattoos or permanent makeup might cause swelling or burning in the affected areas during magnetic resonance imaging (MRI) exams. In some cases, tattoo pigments can interfere with the quality of the image — such as when a person who has permanent eyeliner has an MRI of the eye.
