Bread is good for you, but as with anything we eat too much of anything is bad for you. Notice also if you have bread alot, in the morning you will feel a hole in your stomach, you will be starving in the morning. That's the effect of carbs. But lack of rest and sleep will cause eyebags to droop like bin liners.
But if you serve bread slices to guests, or want to spread something on the bread, wait for its starch to set. On a side note, the second stage of starch retrogradation is the reason why you should use day-old bread for crumbs for thickening, and the third stage is the one which makes bread inedible.
