I would love to CTB by jumping, it would be from somewhere very high (at least 100 meters for concrete impact) and at night time, so that no one sees me. There's a little problem though, the tallest bridge in my country is just 50 meters. That means if I jump, the fall itself won't kill me, but the impact. Not really fan of being concious while my head gets smashed in. Survival instinct isn't really much of a problem with me, I regularly have dreams of jumping from high places. There might be some natural cliff that is 100+ meters tall, however I'm not that outdoorsy to find those places myself. So instead, I will be CTBing by partial hanging.
