What happens at the beginning of Infinity?

This does.

In 2005 scientist at Stanford established that "youthful systemic environment would stimulate bio-rejuvenation in old mice.

Since that time we've discovered that "young blood" contains pro youth blood factors just as "old blood" contains pro aging blood factors.

Both blood factors have been synthesized and recently completed a phase 3 clinical trial to establish the synthetic protein blood factors are safe for use in humans.
We knew they were safe because they're code and the codes are the same - FDA has rules.

Phase three trial showed the proteins were safe as expected and they showed something else.

Have a look for yourself and think about what it means for a civilization to control biological aging and extend human healthspan indefinitely.
