Seat belts are designed and made to fit adults, so if the shoulder belt crosses the child's throat or the lap belt crosses the stomach, the child is too small for it and should stay in a booster seat. Other safety considerations when using a seat belt include never tucking the shoulder belt under the child's arm or behind the child's back. If only a lap belt is available, make sure it is worn tight and low on the hips and not across the child's stomach.

Osteoporosis is caused by multiple factors such as family history, early menopause, sedentary lifestyle, smoking, low dietary calcium intake, and having a small frame.
Women are also at a higher risk.
Caffeine is actually a modifiable risk factor to osteoporosis. Most drinks with caffeine contain high levels of phosphorous. High amounts of phosphorous may weaken bones by pulling calcium from them. High levels of phosphorous also inhibit calcium absorption. A lifetime caffeinated coffee intake equivalent of 2 cups a day is associated with decreased bone density in women who do not consume enough milk or calcium rich foods on a daily basis.
