'Vigorous activity:' Older adults should take caution when shoveling snow, experts say

Nearly 200,000 adults were treated in emergency rooms for snow-shovel-related accidents from 1990 to 2006 , and more than 1,600 deaths were reported in that time frame.

People with heart conditions are more likely to have a cardiac event when shoveling snow.

Adults over the age of 45 "should be cautious" as they stand to be part of an age group that is more at risk of injury, or fatality.
