Hello, I am new to this forum; this is my first post. This subject might already have been discussed but I haven'n found it so here goes. Let's say people in the future live to the age of 200 or even beyond. This would make the population of the world grow to yet unseen proportions. How would we make sure everyone could get food and housing etc? We can't even manage it today. I wan't to make clear that I am thrilled by the possibilities of life extension but I think we have to prepare ourselves. Discuss!
