Longevity is a word that refers to the time that something happens or to how long a specific activity or event will last. The usual longevity of the average movie is two hours or less. There are many longevity quotes out there and these cover everything from speeches to life spans. When you properly maintain a home then it will have more longevity as a result, and the same is true of humans. When you keep yourself in good physical condition and work to stay healthy then you will live longer in many cases. If you but a brand new electric drill with an expected longevity of 5 years but you leave the item out in the rain often then it will not last as long as you could expect it to if it was properly cared for and stored when not in use.
