You won't live forever but it will seem like it.
As for things to do, look up into the sky at the constellation of Orion, where you will see the star Betelgeuse. Born ten million years ago, and giving off every second 100,000 times the energy of our sun, Betelgeuse will - tomorrow or some time in 10,000 years - come to the end of its life, and will go supernova. When it does, it will give off in ten seconds far more energy than it ever did during its lifetime. You'll certainly notice the difference in the night sky.
The supernova happens because during the last day of its life, Betelgeuse fuses some of its heavier elements into a gravity-crushed ball of iron about the size of our Earth but heavier than our own sun. This ball of iron then collapses under gravity. In the next four-thousandths of a second, the iron accelerates inwards to a quarter the speed of light (168 million miles per hour). In the one thousandth of a second after that, it is decelerated to a standstill.
So, eat well, get out, get running, and look at the stars.
