Hard As Nails - Tuesday's Group Run !!

November, one week, painted nails, and answers that become published research.

Here's the shape of it. Before the week there's a baseline survey, ten to twenty minutes. Then in November, any week you like between the 9th and the 29th, you paint your nails and wear them for a week. This is where GoodGym Tuesday comes in! After your week, one more short survey.

Last year 93% of the men who did it said they'd do it again.

Eyes peeled - this will be a fun one.
