Alzheimers Questions

What if everyone caught Alzheimer's ? What if the increase of incidents in recent years is indicative of an emerging epidemic? What if because of too much mercury in your diet or too large of sunspots during the last 50 years the populace of this planet is doomed to a life of Alzheimers? Not able to grasp reality as it is. As if we ever could? What would that mean for a soul? If faced with such a catastrophe. I feel that eventually as the number of afflicted individuals broke the critical mass their would emerge a movement to cure the disease. I do not think drugs alone can stop this thing and man would be one step closer to becoming The Borg.
