Approximately 60 years to go.

Wow. That's a pretty long time to consider if if I were to make it to 81. The year 2071. There'll be what, 30 billion people on the planet? Until then, I'd better find something meaningful to do. Trade 8-5 each weekday for a salary, pay the mortgage, car, insurance, and blow the rest on weekends. Save 10%. Oh right, tithe. Maybe next month.

Wait, I said meaningful, didn't I?
