Earlier this week, my editor forwarded me a video of the leaders of Russia and China talking about immortality. “These days at 70 years old you are still a child,” China’s Xi Jinping, 72, was translated as saying.

Now, several companies have emerged to offer alternatives at a wide range of technical complexity. Read the full story.
