Ultimate Health Tracker

Body Mass Index $($BMI$)$ is a measure of health based on height and weight. It can be calculated by taking

your weight in kilograms and dividing it by the square of your height in meters. The interpretation of BMI

for people $20$ years or older is as follows:

Suppose Ultimate Health Tracker is a member$-$based fitness center that provides customized wellness plans to help

members maintain the proper weight level. They use BMI as the main measurement to decide whether a

customer needs to gain or lose weight. Their goal is to help customers maintain a BMI level between $18\mathrm{.}5$

and $25.$ Ultimate Health Tracker has kept members' information on a paper$-$based file system. Recently, they decided to

digitalize all the members' information and move to a computer$-$based system eventually.

Below are requirement for the system $($i$.$e$.,$ software$)$:

$$ Within the system, each member will have a digital profile containing the member's name, age,

weight $($in pounds$),$ and height $($in inches$).$

$$ The administrator may need to update member's weight over time.

$$ To minimize the maintained workload, the ages should be automatically updated as the year

advances. E$.$g$.,$ if member A was $20$ years old in $2020,$ then A$\text{'}$s age should be automatically

updated to $21$ in $2021.$

Task:

Design the prototype of this system mentioned above using Python. Each member profile can be an

instance of a Member class.

You will need an instance method to update the member$$s weight and an instance method to access the

member$$s age.

To update ages automatically, you might NOT want to keep the age for each member. Instead, you might

keep the year$\_$of$\_$birth for each member. In such a way, when you need to get the age, you may simply

use current$\_$year $-$ year$\_$of$\_$birth.

Create inputs for the following so the fitness center employees can enter each members:

name, weight, height and age

Create an output showing:

Members BMI

name, weight, height and age

BMI Scale to implement

$<18\mathrm{.}5$ is Underweight

$18\mathrm{.}5<=$ User BMI $<25\mathrm{.}0$ is Normal

$25\mathrm{.}0<=$ User BMI $<30\mathrm{.}0$ is Overweight

$30\mathrm{.}0<=$ User BMI is Obese

Note: one pound is $0\mathrm{.}45359237$ kilograms, and one inch is $0\mathrm{.}0254$ meters
