The effortless ease with which we move masks a profound complexity. Join Rodger Kram and Alaa Ahmed, professors of integrative physiology, for talks about movement and aging. Kram will present a series of studies about walking and a new training system. Ahmed will talk about the “risky business” that is movement, aging, and the brain. Saturday, April 18, 1-3 p.m., Benson Earth Sciences – Room 180. Free and open to the public
