In relative terms its a small price to pay for our need for constant connection and access to vast sources of information, earn money and revolutionize the world as we know it. Nothing comes without a trade-off and with a 7billion strong population, a shorter lifespan isn't really such a bad thing in my opinion.
I'd rather focus on enjoying the time I have left on earth than trying to avoid everything that can kill me just so I can squeeze out a few more years.
