#Description:
    #The purpose of this assignment is to create a health calculator. The health calculator
    #is to calculate a BMI value and analyze what it means. The calculator must also
    #calculate the maximum heart rate per intensity level. 
    #The range we will calculate in this calculator is 50%-95%. 
    #The calculator accepts the following inputs:
        #Weight                 (lb)
        #Height                 (in)
        #Age                    (yr)
        #Resting Heart Rate     (bpm)
    #The calculator should return the following outputs:
        #BMI Value
        #BMI Value analysis
        #Intensity Percentages between 50-95
        #Max Heart Rate corresponding with intensity % based on Karvonen formula
    #The calculator will also format the output to make the program's response easy to read 

#Learning Objectives (## means checked off):
    ##Input data from user 
    ##Perform several different calculations
    ##Process data within a loop
    ##Make output choices based on conditional logic
    ##Output information to user
    ##Read string input from the console and convert input to required numeric data-types
    ##Convert math formulas to Python code
    ##Research and apply correct conversion formulas
    ##Understand the if / elif / else construct
    ##Output numeric data to specific decimal places
#I apologize for the messy code.
