I've read speculation that people peak later in quantitive fields, because a discovery requires a lot of work over many years - gathering and verifying data. In math, I guess, advances are made by bright ideas - logical jumps, sudden realizations. The discoverer just needs to read to the edge of the field and then realize something no one else has before. But I think that's a shallow model for inovation. Genuinely innovative companies like Tesla or Skybox mostly seem to be mixed age teams.
