Overlay text read, 'I'm an ER doctor. Name the most dangerous thing in this video.'‌Revealing the answer in the caption, the doctor wrote: "Everyone guesses the tide. It’s the phone I’m filming on."I’m an ER doctor, and drowning is silent — no splashing, no screaming, nothing like the movies. It takes about 20 seconds. Long enough to film one video."Content cannot be displayed without consent‌Giving her advice, she added: "At the water, assign a Water Watcher: one adult, no phone, eyes on the kids, swap every 15 min (or a reasonable interval for everyone), That’s the whole job. Save this before your next beach day."People were quick to engage with the post, as it racked up more than 7,000 likes and 2,000 comments.Many guessed other issues, as one person wrote: "The young children playing close to the water should have some sort of floaters on.

I love swimming in the sea, have done for over 60 years, but you must always be aware of its power."A third suggested: "The colour of the little boys clothes in green, it would be hard to see in the water compared to the red clothes."While a fourth added: "Children have no sun hats on and maybe no sun tan lotion."Article continues belowHowever, others guessed the point the doctor was making.
