Immortality
Humans might be able to extend life to 200 years old or better, with the person experiencing the average health of a 30 year old. Could the world be blowing up because of this? Can we handle living longer? Would that necessarily change reproductive demands? Would that affect employment and retirement and everything about our lives? When does adult become and adult? Per the Kabala, you have to be 40 years old to be eligible to study real magic.
