The Body Mass Index (BMI) is an indicator to help people to determine if they might have a longer life span than average, are probably not overweight, are probably overweight, or are obese. The intervals for each are from 17 to 22, 23 to 24.999, 25 to 29.9, and over 30 respectively. Notice that it is between 17 and 22. That is not inclusive but rather a compound inequality statement which is 17 < BMI < 22. Moreover, over 30 is an inequality statement with a positive infinity which is any BMI that is greater than 30, or BMI > 30 which will be written as (30, +∞). Anyway, my BMI will be calculated, and I will explain …show more content…
Remember that one foot is equivalent to twelve inches. Since I am five feet tall, we will multiply five with twelve to get sixty. Now, I am an additional eleven inches taller than five feet, that is, sixty inches. Hence, we will add eleven inches to sixty inches to make that seventy one inches. The formula …show more content…
It’s no guarantee that one will live longer than usual because, due to some misfortune, he may die in an accident one month later. Or he could be a smoker yet he maintains a healthy weight for his height. In other words, the BMI does not take in factors that are detrimental to his health. So, in order for that to work, there would be a need to construct a more complicated formula to take in account of all the possible factors. Between two persons of different height yet have the same weight, the formula doesn’t take notice of the body fat percentage. A good example is an athletes who weighs a lot for his height yet is much fitter and more trimmed. There is a difference between fatty tissue and lean tissue. Somebody could have a very healthy weight yet has so much fat in the belly while is thin in every other area of the body. Or what if a person is so dangerously thin that he has reached a healthy BMI? Also, age is not taken in factor for the BMI formula. What if one is 95 years old and has a BMI of 21, is he really going to live a lot longer now? It is not an effective formula for children either because their bodies are still
