Tuesday on Lake Effect:
We learn about the field of epigenetics, which tells us our actions can have long term genetic consequences to future generations. Then, we remember rock and roll, and Harley historian Martin Jack Rosenblum, who died this past weekend. Our new fitness contributor offers some advice for people who just joined a gym this year, and we chat with the playwright, star and director of End of the Rainbow, a play with music about Judy Garland currently running at the Milwaukee Rep.
