residents now lack the vigor and zeal a person needs to remain on their feet while performing this 90-second task,” said study co-author Margaret Hollingworth, whose research found that 56% of the nation’s adult population did not brush their teeth while standing unassisted in front of the mirror, up from 40% only a decade ago.
“Of this group, 18% prefer to lean back on the toilet, 15% sit on the edge of the tub, and 20% find that their legs unexpectedly buckle under the effort of standing for more than a minute, forcing them to complete their brushing while sprawled out across a dirty bathroom floor.
