Ann Henninger will talk about “Surviving at the Extremes” at Wartburg College’s next Keep on Learning community education series, beginning Thursday, Jan. 3.

Henninger, Wartburg College professor emeritus of biology, will lead sessions on surviving in extreme environments and surviving the influence of psychoactive drugs.

Classes continue Jan. 10, 17 and 24 in the Heritage Room of Saemann Student Center. Coffee will be served at 9 a.m., followed by the class from 9:30 to 11:30 a.m. Parking is available near Saemann Student Center for those entering campus via Wartburg Boulevard.

Pre-registration is not required. The first class of each session is free; a $35 fee due at the second class covers the rest of the sessions.

Other topics offered in the series will include “The Vietnam War” in February, “To Your Good Health” in March and “And That Changed Everything” in April.

The Keep on Learning series is sponsored by Waverly Health Center. The Wartburg Alumni & Parent Relations Office coordinates Keep on Learning with the assistance of a volunteer committee. For more information, call 319-352-8491, email alumni@wartburg.edu or visit www.wartburg.edu/kol.
