If i was stuck on an island what 3 things and 3 people would i bring?

Someone who I would bring with me is my Swiss grandfather; he was a police officer in Switzerland and an outdoorsman. His back ground as a police officer would help us with a sense of government. We would establish rules and he would enforce them. His outdoorsman ship would help us with overall survival. Another person who I would bring is my next door neighbor Oscar. Oscar is a frequent camper and an athletic person. He is an independent person and doesn’t get scared easily so we could send him out as a scout to look for recourses. He is strong so he could be a good worker. His slight sense of humor would also keep us sane. Finally I would bring my other next door neighbors friends mom. She’s a fully trained operating room nurse. She could be our medical person. She is also a good leader and planner.
Something that I would bring is a satellite phone. This phone would get a signal anywhere in the world. With this phone we could call for help. These phones are usually built tough so it would probably last us a long time or at least until it runs out of battery. I don’t think that would be a big problem because satellite phones have about 30 hours of battery life. I would also bring a crank powered water purifier. We would use this as we wait for rescue. This would come in handy because humans need water to live and it has other uses too, for example cleaning wounds and clothes. Clean water would also help us stay healthy because it will have no bacteria. Depending on how much water we have to spare we could cool off with it. It would also help with food. If we found potatoes we could boil them so they are edible. Finally I would bring a big box of tools. We would bring the tools to make shelter and other useful things. They would also help us collect food. If a tropical fruit was strongly stuck on a tree we could use a small saw to cut it off. Tools would also be useful when we need to defend against animals. The tools could also be useful for medical purposes.
