In movies, kings are always searching for the secret to immortality.

程度の副詞

To a ten year old boy, one year is the same as 10% of his life.

To his forty year old mother, one year is merely 2.5% of her life.

The same year, 365 days, can feel differently to different people.

If we live until we're 82, that's about 30,000 days.

If this boy lives for 30,000 years, a year to him could feel like a day.

And if this boy's emotions sustain through the potential boredom of living for millions of years,

knowing he has and always will outlive everyone he has ever loved.

How much of your past have you forgotten?

If you're having trouble remembering what you did when you were five,

how will you remember what happened if you were alive a thousand years ago?

We don't remember every single detail of our past

because our brains have a limited capacity

If this immortal boy finds a companion to fall in love with once every hundred years,

he would have ten thousand girlfriends in a million years.

And how many of those ten thousand girls' names will he be able to remember?

This changes what a meaningful relationship means,

Human beings have not always looked the same.

This can be explained by Darwin's Theory of Evolution.

For instance, if women find taller men more attractive,

then more tall men would mate and have children,

putting more tall genes in the gene pool.

That means, in the next generation, more children will have the genes to be taller.

Repeat that process for a million years and the average height will be a lot taller than the average height today,

We still have body hair, but we don't look like apes any more.

If you're the only person who is immortal,

while everyone else keeps evolving generation after generation,

you will eventually look quite different than the people who surround you.

If one of our ancestor apes is still alive today,

how many people will make friends with it instead of calling the Museum of Natural History?

And one more physical consideration for immortality:

After all, immortality doesn't automatically translate to invincibility,

But it doesn't guarantee what condition you'll be alive in.

If you have made this many permanent scars within your life,

imagine how much damage you would have if you were one thousand years old!

185,000 amputation related hospital discharges every year in the U.S.

These injuries are due to accidents or illnesses.

However, if you've been alive for over one million years,

the odds of still having all your limbs are pretty slim.

What are the odds of you keeping your dental health

You might end up looking like a horribly scuffed up Mr. Potato Head

So, are you sure you want to live forever?
