while it's still easy.

There will come a day when getting out of bed will be an obstacle. A struggle that actually takes work to do each day. A day when our bones are no longer strong, our hearts are no longer beating as quickly, and our muscles are no longer as tight and useable.
Next time you sleep half the day and then spend another hour contemplating even getting out of bed, remember that it's as easy as rolling over and stepping off to start your day. No second guessing whether your knees will give out as you stand or if that pain from yesterday will jolt back as soon as you make an effort to move... Get up and make use of the time you have. While it's still as simple as rolling put of bed, jumping on the shower and and conquering the battles of the day.
This life is a gift. Our bodies arnt getting any younger. Don't let too old and brittle sneak up so soon, leaving you wishingyou would have made use of the time you had when you were still young and healthy.
