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.
Best Answer: The average person will lose about 150 calories a mile. so walking 4 miles will lose 600 calories. Note; if you are normal weight or 10lbs over weight, you may lose a little less, 500 calories for 4 miles, but if you are 50lbs or more over weight you will lose more, 800 calories for 4 miles.
