Longevity.

 In recent months a number of the technology billionaires like Mark Zuckerberg, Elon Musk and others have been - thinking of ways to extend their lifespan into the hundreds. Going against the natural ageing process which determines how long - we will live for. The general consensus about the upper age limit is roughly between 115-125 years. It’s unlikely that anyone will live beyond this range. The reasons are: damage to our DNA, the likelihood of some fatal disease or other, a fall or accident - can be the precursor to death. The question is - why would you want to live beyond this natural span of time? Very probably your closest friends will have died before you, family may live a long way away, and the clock is ticking anyway.
