Airbags， now found in almost every vehicle， have saved countless lives and largely reduced the severity of injuries in crashes. Similar technology could greatly reduce broken hips resulting from a fall， something most seniors fear.

Dr Robert Buckman and his start-up company， Activeprotective in Allentown， Pennsylvania， has developed a promising solution， a wearable airbag that can protect hip bones in the event of a fall. The idea was the result of Dr Buckmans years as a doctor at Temple University. He noticed how many elderly people were being brought into hospitals with broken hips due to falls， and how they often never completely recovered from the injuries. He started to ask what he could do for these people， and that was when he started trying to figure out whether there was a way of helping people who were at the highest risk of falling and suffering these kinds of injuries.

The device is worn much like a regular belt， but on the outside of the clothing， and it includes sensors that monitor the movement of hips. If the device detects that the person is falling， an airbag opens before the person hits the ground， cushioning the fall. When the wearer hits the ground， the bag reduces the force to the hip bones by 90 percent， enough to avoid the majority of hip injuries.

With one out of every three people aged 65 and older suffering serious falls each year， Activeprotective has a big market for its wearable device. It also has the potential to sizably reduce hip-related health care expenses： Hip injuries among the elderly cost the US health care system in 2012 $30 billion， which doesnt include the long-term care expenses associated with the high percentage of patients that can no longer live independently.

All of my five children played team sports in middle school and high school， and four of them are in college. 1

Teenagers may get into bad habits. 2 According to a study in Archives of Pediatric & Adolescent Medicine， a survey of more than 14，000 teenagers found that those who had taken part in team sports were less likely to smoke or have unhealthy eating habits.

As children get older， they naturally develop their own lives and there will be fewer ways for parents to be involved （參與）. Some teenagers shut their parents out of their room. 3

Sports build strong and healthy bodies. Children who compete know that they are only at their best if they eat and rest well. 4 In sports， strength and speed are wanted. Team sports help kids avoid obesity （肥胖） problems even better than activities like running or biking.
