One should be able to estimate this for men and women given current statistics on accidents and violent deaths.
If one was to catch the wrong breath and get infected by a virus that eventually led to their death, would that be an accident or natural causes?
If 1% of people die non-naturally, people would get around 100 times as old. If it's 10% they would get 10 times older.
That means every year you have a 1/10,000 chance of dying, so on average people would live 10,000 years
