Lifestyle - interests, opinions, and behavioural orientations of an individual, group, or culture.
Personal lifestyle typically reflects individual attitudes, way of life, values, world view, and personal identity. Not all aspects of a lifestyle are voluntary. Surrounding social and technical systems can constrain the lifestyle choices available to the individual. Location is important factor of lifestyle. The nature of the neighborhood in which a person resides affects the set of lifestyles available to that person due to differences in degrees of affluence and proximity to natural and cultural environments.
Lifestyle may include views on politics, religion, health, and intimacy.
For example, "green lifestyle" means holding beliefs and engaging in activities that consume fewer resources and produce less harmful waste, and deriving a sense of self from holding these beliefs and engaging in these activities.
Vitamin B3, Niacin, nicotinic acid, helps to convert food into energy and is essential for healthy skin, blood cells, brain, and nervous system. It is one of 8 B vitamins. It is water-soluble, which means it is not stored in the body. It has 2 other forms, niacinamide (nicotinamide) and inositol hexanicotinate, which have different effects.
Niacin occurs naturally in food and can also be made by your body from the amino acid tryptophan, with the help of B6.
It is rare for anyone in the developed world to have a Vitamin B3 deficiency; alcoholism is the main cause of it in the US.
