i can sharpen knives easy, learnt that when i was young, can also throw my knife fairly well. Can catch feral animals that roam my neighborhood (cats/possums). Can skin animals.
Can shoot a gun accurately with 10mins to an hour of practice, can fix clothes although sometimes i do a horrible job, perform basic carpentry, strip and clean an engine, destroy an engine quickly (angle grinder ftw!!), can cook meat and make good salads, perform maintenance on most electrical appliances and other things i cant remember atm.
Out of all these things only sharpening knives/cooking/fixing clothes where passed on to me via parents, the others i learnt of mates, work or recreational activities.
Also manners needs to be brought back, so many rude 14-18 yr olds here.
