The disease does not appear to spread from a mother to her baby at birth. The main symptoms are a fever, a dry cough, shortness of breath, or difficulty breathing. A person with SARS also may experience a headache, muscle aches, a sore throat, fatigue, and diarrhea. An older person may feel generally unwell (malaise) and lose his or her appetite but not have a fever.
Figuring out how many calories you burn when running is, on a simple level, a fairly straightforward calculation. Most experts (and lots of studies) suggest that a person of average weight burns about 100 calories in a mile of running.
When it comes to walking or running, people tend to burn between 80 and 100 calories per mile, no matter how fast or how slow they are. Half an hour of walking at a casual, walking-the-dog pace (2.5 mph, or a 24-minute mile) will burn about 97 calories. A brisk 4-mph stroll (15-minute miles), on the other hand, will burn about 161 calories in 30 minutes.
