Being Active As A Preschooler Pays Off Later In Childhood

Makes sense, but not for the reasons the researchers give.

"Being active at age 5 helps kids stay lean as they age even if they don't remain as active later in childhood, a new University of Iowa study shows.

"'We call this effect 'banking' because the kids benefit later on, similar to having a savings account at a bank."

The real reason is an effect called "good parenting" and is accomplished by nurturing a culture, at home, of responsible fitness behavior that is reinforced over the years and remains with the child for life.

There is no other magic at play here.
