You mean, how do I rationalize myself staying here? My family happen to still taking care about me so I don't have to face homelessness, starvation or poor hygiene as a result of sitting on my ass all day not doing anything productive, and my emotions happen not to be intense enough to motivate me to do something radical with my life, and my primitive brain happened to still be fully functional and is working overtime whenever the lethal danger is identified.
These are just proximal reasons, and behind them would be reasons causing them, and behind those another layer of reasons, and so on. At some point there would be bottleneck reasons, where one thing would make all the other reasons irrelevant, like my death, or death of my parents before giving me birth, or death of their parents before giving them birth, and so on.
