young people die from all kinds of stuff.
we are not immune to death. young people gets cancer.

but if you think of whats best for the human race
thats natural selection. as we have done millions of years.

human body adapt and evolve.
to let a foreign substance be "needed" for the human race to survive will make our own body weaker and weaker, until we need to get a shot every day to survive.

we already do that, people eating medicine more and more. and its increasing.
big pharma wants this, for profit.
