Answer: "Normal" ranges for pulse in any person at any age varies quite a bit. Pulse varies even more than blood pressure measurements, and changes second-by-second. At rest, a baseline pulse is typically 60-70 beats per minute. Tachycardia is usually diagnosed with a continuous pulse rate of 100 or over. It is not uncommon, however, for either older persons, or well-trained athletes, to have a resting pulse rate as low as 45-50. This reflects a well-conditioned cardiovascular system in the athlete, and possibly a lower BMR (basal metabolic rate) in the elderly. Low pulse rates are usually not a health concern unless they are related to fainting, or possibly to certain medications which may require dose adjustments.
Answer: I think that really depends on the router or the wi-fi device. It usually should go up to about 25-40 feet, it depends really. You get better service and lag the closer you are but not too close, so the optimal place would be about 5-10 feet away
Answer: The value is usually represented by a percent of WBC (white blood cells) and the range varies according to measurement method, laboratory and other. Some labs accept as normal values 22-50%, other 16-45%. As a value, their count can be 1000-4000/ul (ul=microliter) or 700-4800/ul (these values are considered normal for adults)
