Maybe it's time to invent something that can help us avoid jellyfishes while swimming. Recently, I saw a video about a device that releases small amount of current when there are sharks around. It's called Shark Shield. It was put in the ankle of the surfer and when the shark was heading to his direction, the device expelled current that cause it to turn away.
There are actually several things. Gels that are supposed to neutralize the toxin (apply before swimming), suits that can't be penetrated by the tiny hooks...
Thing is, you have to buy and actually apply/wear it. How regularly do you apply sunscreen? Do you always wear your helmet on the bicycle? Even if the answer is yes, you'll do other dangerous things.
People just don't think about the dangers. I didn't either.
Well that maybe is the problem, we like taking risks without calculating the dangers first and we think more about spending money than our own protection. Although I think It’s not like we’ll only be using it once. You’ll be swimming again right? Prevention is still better than cure. Just be careful next time. Get well soon @suesa.
