Anyone who's been thin or normal weight range

C:
Have always been skinny, in-fact I'm the only one among family or relatives that is.
I attribute it to being productive in my youth or even now in my old-age.

Many a time worked three jobs consecutively in a day.

How it all came about
One night sat in a Bar, and noticed if I've that much energy to party all night than I could be doing something else instead of spending it all.
One Job led to another and yet, another.

Now, I'll find things to do around my apartment to keep me busy, like when things get dingy bathtub, kitchen sink all cabinets and even the walls.

That way, its easier to maintain than the usual monthly clean-up.

Managed to keep weight to 140 since high school.
