This is where science comes in handy...
You are 99.5% the exact same as the people around you. As humans, we're nearly identical, BUT that tiny 0.5% can make all the difference in the world.
To put this in perspective, your genes are 90% the same as those of a cat, but obviously you and Garfield are SO different.
The smallest genetic differences lead to dramatic uniquenesses. That's why you are YOU.
Now you can understand why figuring out your specific genetic uniquenesses is like being handed a key that unlocks your personal fitness code.
