LONDON (TG) Women look their oldest at 3.30pm every Wednesday, a study has found, because that is when energy levels plummet, work stress is at a peak and the effects of any weekend late nights finally kick in. The research shows one in ten women (12 per cent) find Wednesday the most stressful day in a typical week. A quarter of women feel stressed several times a week - while one in five (19 per cent) admit they will work through Wednesday’s lunch hour.
