A neurologist has detailed the three things he never does outside of work as a result of what he's learnt in the field.
Dr Baibing Chen, who goes by Dr Bing on social sites such as TikTok, is known for providing advice to patients and thousands of people on the web.
Of course, it's always advised to book an appointment with your GP if something is wrong, but Dr Bing's quick and simple videos shared online can provide much needed answers for patients from the comfort of their own home.
While he has previously detailed a two-minute test that could explain if you have early signs of dementia, Dr Bing has now detailed the three things he would never do.
Sharing drinks
The expert stated in a viral video how he doesn't 'share drinks' with people he doesn't know.

He explained: "For some people, this is obvious, but for others it sounds harmless. Passing a cup around at a party, taking a sip from someone's cocktail, but I've seen what it can lead to.

"Beside the risk of drugs being slipped into drinks, you can pick up all kinds of pathogens. Not just herpes, but also things like mono and enteroviruses. All of which can affect the brain."
Providing an example, Dr Bing went on to say he once treated a young adult who had developed viral meningitis after spending a weekend at a music festival sharing drinks.

"They thought it was just a hangover until they started seizing," Dr Bing explained.
The doctor noted that while some may see it as an 'overreaction', he will always be getting his own glass at gatherings.
Masks
While it may sound like we've stepped back in time to the Covid-19 pandemic with this one, Dr Bing admitted he doesn't skip wearing a mask in 'dusty or enclosed spaces'.
Advert
He explained: "This is because I've seen fungal infections like histoplasmosis and cryptococcus start this way."
Worst case scenario, these infections can cause meningitis or encephalitis months or even years later.
"You don't need to be splunking in a jungle to get this," Dr Bing continued. "Just cleaning an old attic or sweeping out a shed can be enough for some people."
Advert
However, it should be worth noting this is extremely rare and not a worry for most people.
Honey
Finally, Dr Bing explained how he would never give honey to infants under the age of one.
The expert said: "It may seem innocent, natural or even healthy but honey can carry clostridium botulinum spores. In adults and older kids, our guts can usually handle them, but in babies, those spores can germinate, produce toxins and lead to infant botulism - a rare and life-threatening condition."
