run for what?

run for what?
Of course I can't find the best answer.
eat for what? work for what? play for what?
And live for what?
...... maybe many answers, so life is exciting!
While running in the daytime I can enjoy the scenery that I can see, but at night there are few things I can look out over, so I have more chance to think about everything.


Today's training: 15km jog& slow run?
Monthly mileage for February: 63km
