Lived human experience, expressed in linear time (years) is rather data poor, meaning most of life is informationally empty. Consider the person who never leaves his hometown... He goes to school, gets a job, a family, and stays roughly in the same place he grew up, repeating the same routine. He effectively stops being exposed to new experiences and info at... 35? When he's 55, he doesn't have 20 more years of data... He has 20x reinforcement on 1 year of data. On repeat. Forever.
