So much quantity of food and processed foods that were not available even 100 years ago.
People are eating more, and more of it is highly processed, and people are eating more late at night, watching late night TV or whatever while they eat, and what with more comfort food being available due to food storage what it is today compared to years ago and even peoples standards of living now compared to then, government programs today, food stamps, etc, we can afford more food and eat more.
Add that to the stress of living today, and the EMF's, its no wonder people are getting sicker sooner and more often.
And if anyone uses the argument of life spans being longer, don't let them mislead you. If one looks at the rate of infant mortality, which was factored in to average ages then and now, people back then actually lived about as long as today and in much better health.
Today thanks to meds and operations we are keeping people alive longer then we could have years ago, but they are physical zombies. Who wants that? Not me.
