30 minutes of moderate aerobic exercise boosts neural processing of semantic memory (memories that relate to language, words, and names), finds a new brain imaging study (age 55-85), which suggests that a similar workout just before a test requiring semantic memory might improve your performance.

Optimism is lowest in people's twenties, rises steadily into people's thirties and forties, peaks in people's fifties, and gradually declines after that, suggests new research (n=1,169) that charts the trajectory of optimism over the lifespan, which found people experienced peak optimism at age 55.
