Virtues of the parents visited on their children

I came across this interesting article that described how (in mice at least) exercise by parents could transmit benefits to their offspring.

Key point: "...male mice who exercised produced smarter babies than their nonexercising counterparts."

Other points:

• "...factors like diet, stress and exercise can modify the behavior of the genes parents pass down."
• "Gene behavior can change when genes, which are made of segments of DNA, are activated or silenced."
• "Physical and mental exercise is known to benefit human learning, but future studies will have to determine if learning abilities can be inherited in humans."
