Time Dilation and Human Lifespan

What percentage of the speed of light do you need to go for a single year flying in space to equate to a average lifespan of say seventy years here on Earth? Science question, some whimsical philosophical side also.
See the endless dead rise, see them rise, it is their final day and they know nothing of it.

Using the Lorentz factor, the percentage of the speed of light needed should be around 99.99% to achieve a 1 in 70 time dilation.
