Whether you think it's cute, or it makes you squirm, baby talk is a compelling scientific phenomenon. All around the world, people use a special register when they speak to the very young.

Bilateral leg edema is swelling of the soft tissues of the legs. The condition can be merely a daily nuisance, or signal a serious underlying condition. A physician should be consulted to determine the cause and begin appropriate treatment.
For example, when leg extensions are the agonist exercise, lying leg curls are a good antagonist exercise (since the hamstrings are antagonists to the quadriceps). It's not the best pairing, though, because leg extensions are performed while seated, and lying leg curls are performed while curls are a good substitute.
