Drive because lazy to walk? or Lazy to walk caused by drive?

Today I went campus earlier to avoid park my car too far from campus but finally I parked my car near Domino’s.

I grumbled about I'm so tired to walk so far with bringing laptop under dazzling sunlight. Moreover, I went up to the stairs of third floor for two times today.

In fact, I'm walking to school everyday when I was studying secondary school.

I almost forget about those years I walk everyday even I’ll run while rushing on time.

I'm wondering why I become so lazy? Because I became a driver?

We’ll park at most nearest parking lot to avoid walk from far.

Actually we already drive a long distance help to walk less, shouldn't we walk more just for exercise purpose?
