Imagine by chance you've became immortal, you don't know how but you're the first and as far as you know the only human that doesn't age. How much time do you have before you're forced to do something illegal or drastic to avoid becoming a guinea pig?
A long life is coveted by almost everyone, and as soon as your secret is out, you'll become the ultimate target for people who want what you have. Amongst them is the most powerful and the wealthy, and almost nobody is there to protect you.
Those whom don't have enough money and power would try to make some money of you and there's plenty of people who would pay them, even those close to you might want a chunk of you! Running and hiding is not as easy as it was and without law on your side you're just sitting duck.
It is a highly unlikely hypothetical situation but this mind experiment helps you understand how vulnerable you are an how inadequate is the law when you possess something valuable enough.
I've seen people dismiss all warnings about their privacy thinking "I have nothing to hide", if you're one of them, rethink your position before it's too late..
