The thing about the jellyfish is just wrong! Their stings are painful but as long as ur not allergic to the toxin you won't suffer severe consequences (except a little bit of pain). Also: They are not very common in the summer months and their toxin (protein) can be inactivated with warm water 50°C. I visit the Azores every summer and have been stung 2 times over the last 10 years. (I stay there 2months each summer and the beach is my go to place)
Join the Air Force. Get stationed at Lajes. A 12 month assignment is not enough time to see everything. I was there for 8 years. It's fantastic. Many of the amazing places that I'd tell you about, you may be tempted to think that I'm lying to you....
