An expiration date or expiry date is a previously determined date after which something should no longer be used, either by operation of law or by exceeding the anticipated shelf life for perishable goods. Expiration dates are applied to selected food products and to some other manufactured products like infant car seats where the age of the product may impact its safe use.

If you have tight shin muscles or pain, you may want to spend some time stretching your anterior tibialis muscle. This muscle is at the front of your lower leg. Its action is to flex the foot upwards, as well as to control the foot as it lowers back to the ground. This muscle mostly gets a workout when running, walking, and in sports such as tennis and basketball, which have a lot of little sprints.
