Young peoples' bones stop growing by approximately age 20, somewhat earlier in women and somewhat later in men. Long bone growth, that is, in the arm, forearm, thigh, and leg, ceases later and smaller bone growth, that is, in the hands, feet, and spine, ceases earlier. In essence, you're as tall as you're going to be by your mid- to late teens, and at the latest, by approximately age 20 or so. A great deal of a person's height is comprised of the length of her or his spine and approximately 25% of the length of an adult human spine consists of the thickness of the intervertebral discs.

Spring is arriving. The days are getting longer, the air is fresher, and the sunlight is brighter. Flowers and bushes are beginning to bloom. Tree sap is running and there are new baby animals in the world. In short, the world is being renewed and, if we choose to, we too can actively participate in this process of rebirth and rejuvenation.

Children and adults are the same but different. Most kids want to play all the time, but they also are required to go to school. Most adults would prefer to play all the time – relax, go to the gym, read a book, watch TV, or get together with friends – but most adults need to go to work at least 5 days a week. Interestingly, what most young people don't know about adults, especially older adults, is that they think of themselves as much younger than they actually are chronologically. For example, long ago, when a reporter asked the great golfing champion Arnold Palmer how he felt about turning 60, he famously replied that "it doesn't matter to me, I think of myself as 27." Thus, speaking broadly, kids and adults share similar primary goals. Regular chiropractic care can enhance the quality of life for both young and older people by helping make possible the attainment of high levels of overall health.

Concussions are becoming increasingly common, especially among school-age athletes. It has been estimated that there are up to 3.8 million sports-related concussions in the United States each year. Concussions are problematic as, by definition, a concussive injury involves some degree of trauma to the brain. A concussion injury literally jolts the brain, causing this precious organ to bounce against the bony walls of the skull. The violence of the blow directly determines the degree and extent of brain cell damage. Importantly, any person can experience a concussion from having sustained a blow to the head. Falls are commonly implicated in a concussion history, especially in those who run or walk for exercise and may trip over a crack in the sidewalk or a hidden tree root on a trail, as well as in the elderly.

In the depths of winter, adults, as well as children, exert themselves to engage in enjoyable outdoor activities that will keep them warm and provide both excitement and entertainment. Cross-country skiing, downhill skiing, sledding, ice hockey, figure skating, and speed skating all have their enthusiasts.
