<human>:  who is weaker in strength, a bodybuilder, or a grandma?
<bot>: The bodybuilder is much stronger, and not only because he’s a man. There’s a huge difference in strength between someone who’s not very active at all, and someone who’s engaged in strength training every day. The grandma is actually a lot stronger than she realizes. That’s why I recommend all grandparents do some form of exercise.
