Janna used to go biking every other afternoon with her sister, but she had to stop this because she started an afterschool job. what consequence will janna experience over time if she does not find a similar activity to replace the biking?

The answer you might be looking for is that, for one, she will feel guilt over not riding with her sister anymore, and that she might experience some health issues because she doesn't ride anymore with her sister. In order to avoid these consequences, Janna should look into other sports or activities that she can balance out with her job and her sister.
