The age of the sum of the body parts doesn't always equal the age of the whole's mind. As colorfully pictured and cleverly worded on the timelessly hilarious Happy Birthday card available here. Those more than mature, older, elderly and/or senior citizen friends, family members and colleagues of yours will still be able to comprehend, fathom and greatly appreciate the good humor and garrulous mirth featured on the funny and fabulous looking Birthday greeting using their young and agile minds; even if their aged, ravaged, pain riddled bodies can't "quite" bend over backwards with laughter anymore.
