This week's dispatch

Come and stay, but leave before the balloons deflate.

We've all heard the same advice around this time of year when company holiday party invitations abound. Don't drink too much, don't sit in a corner, and don't wear something inappropriate.

Still, one piece of advice that may have gone in one ear and out the other is strictly about timing. When you arrive at your company's holiday party — and when you leave, for that matter — is just as important as the other oft-told advice you've probably heard.

Professional etiquette expert Diane Gottsman told writer Alyshia Hull that employees should feel that company parties are mandatory. And even if you don't feel like going, being the first to leave is not OK.

"If you get there and you leave 20 minutes later, people are going to notice," she said.

Still, being the last to leave is also a bad look, Gottsman said. If you don't want to leave your coworkers, she suggests going to another location to keep the party going.

Have fun!

White-collar men's beauty secrets

Men in corporate America want to look good at work — and they're spending thousands of dollars to do so. They're getting routine botox procedures, pricey hair-loss treatments, and splurging on time-consuming routines, all in an effort to gain a competitive edge at their job.

Still, many of them remain uncomfortable discussing the intensive procedures they're getting. BI spoke to four corporate men who are spending loads to strike the perfect balance of a youthful, experienced appearance.

The rise of "brotox."

Young people want their grandma's bathrooms

Neutral-colored, "modern" bathrooms are out. The old-fashion look, which typically features pastel colors with intricate tiles and frilly decor, is back.

Once considered dated, "grandma bathrooms" are driving homebuying and interior design trends, even among millennials and Gen Z. Some homeowners are spending thousands to restore their bathroom's original vintage look — or they're paying extra to re-do the space altogether.

Bathrooms go granny.

A personal trainer's daily supplements

New York-based personal trainer Don Saladino, 47, has worked with celebrities, including Ryan Reynolds, Blake Lively, and Anne Hathaway. As someone who takes his health and fitness seriously, Saladino told BI he's dedicated to eating and training optimally — and said he's stronger now than he was in his 20s.

Aside from training, nutrition, and sleep, supplements are also a part of his lifestyle. Saladino shared the 11 he takes every day, from creatine to magnesium.

His supplement regimen.

A meal in Musk's Kitchen

After making millions in 1999 from a deal with his brother, Kimbal Musk attended culinary school in New York.

Five years later, the younger Musk went on to open a restaurant with chef Hugo Matheson in Boulder, Colorado. The Kitchen Group now has restaurants in Chicago, Denver, and Austin, Texas. Emily Hart said lunch at the original bistro in Boulder lived up to the hype.
