<h1>Animal Years</h1>
38+
<p class="subtleHeading">Problem written by Lucia</p>
39+
<hr/>
40+
<p>
41+
Other animals typically have different lifespans than humans. If you divide the average human lifespan by the average lifespan of another animal, you can calculate the multiplier for converting an age in human years to an age in animal years. For example, the average lifespan of a human is 79 years and the average lifespan of a dog is 11 years. So, 1 human year is equal to 79/11 = 7.18 dog years. Then, to convert say 3 human years to dog years, you'd multiply 3 * 7.18 = 21.54 dog years. That means, if your dog is 3 years old in human years, they're past their teenage years in dog years!
42+
</p>
43+
44+
<p> Write a program that converts human years to animal years (of any animals of your choosing!):</p>
45+

55+
<p>
56+
Since the multipliers for each animal will never change, you should store these as constants.

<h1>BMI</h1>
38+
<p class="subtleHeading">Problem written by Neha, discovered by Adolphe Quetelet</p>
39+
<hr/>
40+
<p>
41+
The BMI is a convenient rule of thumb used to broadly categorize a person as underweight, normal weight, overweight, or obese
42+
based on tissue mass (muscle, fat, and bone) and height.
43+
<br/>
44+
Commonly accepted BMI ranges are underweight (under 18.5 kg/m2), normal weight (18.5 to 25), overweight (25 to 30), and obese (over 30).
45+
</p>
46+
47+
<p> Write a program that continually reads in mass and height from the user and
48+
then outputs if the user is underweight, normal weight, overweight or obese. Show your work in the following way:</p>
49+
<p></p>
50+
<center>
51+
<img style="width:400px" src="./demo.png">
52+
</center>
53+
<p></p>
54+
<p>
55+
If you ask the user to input weight in kilograms (m) and height in meter (h),
56+
the result of calculating BMI = <i>m</i> / <i>(h * h)</i> will be in kg/m<sup>2</sup>.
57+
The program will then output if the user is underweight etc based on the BMI.
