At the top of Maslow's Hierarchy, there's a hidden door on the roof which reveals a new level:

• Life extension. For yourself and everybody else.

So sad watching people age and die of diseases.

Irony:

The hidden door at the top takes you back to the bottom of the pyramid.

Survival.

Whoever makes breakthroughs in the life extension space will be a trillionaire.

Warren Buffett would give all his money for 10 more healthy years.

But the wins are greater than financial... It's seeing loved ones live longer.

Life extension: A potential product with unlimited inelastic demand from every single person.
