One of the reasons Blue Monday lands in January is because it's a month of self-imposed deprivation. From Dry January to Veganuary, if something brings enjoyment to your life let's ban it for a month.
And we do this at a time when the nights are cold and dark and a lot of us have tax forms to fill in.
Each year there's a health fad to join. I remember when it was dried goji berries when we all paid over the odds for something resembling a witch's bogey. There was kale last year which is the only thing that can make spinach seem exciting.
Manuka honey was all the rage one year, which is expensive stuff. It hurts when you look at your manuka honey receipt and your self-assessment form and notice you earn less per hour than a bee.
Thankfully 2017 could see the best health fad yet. Research says coffee makes you live longer.
People often to say to me I drink too much coffee. Now I know they want to be die sooner.
Scientists found a link between people who worship the bean, as I do, and staying alive longer but have only just come up with an explanation. There is something in coffee that is an anti-inflammatory, it reduces swelling.
So I will be sure to offer a coffee to the next person who tells me I drink too much, because they're going to need it.
