Weight:height.: The BMI is simply your weight with respect to your height - an overly simplistic and thereby essentially flawed assessment of your health. It's a bit better when used in combination with body fat measurement. That being said, a high BMI might be associated with diabetes and heart disease amongst other health conditions.

Pinky toe: Although it may not be structurally the most "fragile" bone in the body, the most often broken bone in the body is the 5th (or pinky) toe. In some sports, like sailing, the pinky toe is broken in 50% of athletes who are involved in the sport for more than 2 years.

Does your body get used to the fitness if you run every night?

Yes!: You will accommodate and will not have to work as hard so you will not get as good of a workout. I am a big advocate of hiit (high intensity interval training) and recommend you add hill work or some sprints to your workout to challenge yourself - 30 sec sprint with 90 sec jog works well x 8. This workout also enhances natural secretion of growth hormone and increases your resting metabolism.

All depends: 1) do you take narcotics regularly? Your system will metabolize more rapidly. 2) are you asking how long they will provide effect? Typically 4-6 hours. 3) are you asking how long will it be before you test negative on a urine drug screen? Probably 2-3 days.
A 38-year-old member asked:

How long will pseudoephedrine last in your body?

1 doctor answer2 doctors weighed in
Dr. Thomas Benda, jr
ENT and Head and Neck Surgery 34 years experience
Depends on dosage: The bottles are usually labelled as to how long they last. 60 mg is marketed to last 4 to 6 hours, 120 mg 12 hours, and 240 mg all day. The generics may not work as a sustained release tablet as well as brand name drugs here. Pseudophedrine can cause palpitations, jitteriness, insomnia, and high blood pressure. By about age 40 i tell most people not to take it with any regularity.

Can you tell me how could BMI (body mass index) work?

Dr. Alan Feldman
Endocrinology 41 years experience
Bmi: Bmi is a calculation based on your height and weight. Normal is between 18 and 25, overweight is 25 to 30, obese is 30-40, and morbidly obese is above 40. However, if you are very muscular, your bmi will be higher than normal, even though you are not overweight.
