One’s age can be revealed by how they consume biscuits alongside a hot beverage.

The way you eat a cookie with a hot drink may betray your age, research has suggested.

Researchers found that 83 percent of adults prefer dunking when eating a chocolate digestif; however, the techniques vary from generation to generation.

Four in 10 Gen Xers — those ages 43-58 — and a similar proportion of millennials ages 27-42 like to break their cookies in half and eat them — while the older group usually gobbles down the treat in four bites.

Meanwhile, 16 percent of Boomers — those over 58 — like to slowly nibble their cookie around the edges and work it in, the Galaxy Digestive Cookies study found. Gen Z, those 26 and under, are the biggest tea drinkers (63 percent), while millennials prefer to dip their cookies in coffee.

The survey also revealed how Generation Z likes to eat their cookies, with 38 percent choosing to dip twice and half saying they like to dip in tea for two seconds. Five cookies were eaten on average at one time.

It comes as McVitie’s launches a campaign to reinstate the office tea and biscuit break, as research shows overworked employees are so busy they don’t even know their colleagues’ names.

The biscuit brand – which has partnered with mental health charity Mind – commissioned a survey of 4,000 working Britons to understand how the cultural institution of the office tea and biscuit break has crumbled in recent years.

The survey showed that 70 percent of employees take less than 15 minutes of breaks – outside of lunch – and 40 percent less than 10 minutes.

It also found that 93 percent believe a tea break is an important part of the working day, with more than three-quarters (76 percent) feeling their performance at work is compromised if they don’t take enough breaks.
