Everyone needs some exercise in order to maintain good physical health. While anyone who exercises will reap a measure of rewards, it is perhaps those who are age 65 or older that may receive the most benefits. Age affects our mobility, strength and agility. Regular exercise can help counter the effects of aging, which in turn can help older individuals maintain their independence.

Walking is one of the best ways for older adults to get a workout. For one thing, walking is low-impact, so it does not put too much stress on the body. Also, it is convenient; you don't need a gym membership to take a stroll around the block.

However, older adults are also more vulnerable when out and about. This is especially true when crossing a street. It is far more difficult for an older pedestrian to move out of the way of a speeding vehicle. What's more, because older adults are typically more physically frail, any injuries they suffer from being struck by a car, truck or even bicycle may never fully heal.

According to information published in an AARP Bulletin magazine in 2012, 20 percent of all fatal pedestrian accidents were suffered by people age 65 and over. Those in this age group comprise only 13 percent of the population. This disproportion illustrates how truly exposed older pedestrians are, and that motorists must always look out for them as they cross the street. This means driving at posted speeds and slowing down when necessary.

If an older member of your family has been struck by a car or other vehicle while out on a walk, it is important that they receive the care they need. If the accident was due to negligence on behalf of a driver, then he or she should be held accountable. Depending on the circumstances of the accident, you may wish to pursue a civil suit against the responsible party. A personal injury attorney could assess the situation and may be able to advise you on a course of action.
