Our bodies are just vessels. No different than our cars or our houses. They are simply the “thing” that carries around our soul/heart/mind/life force.
We should not get hung up about them. We should do what we can to look after them – they are with us for the whole of our life. We can do various things to improve their condition and their appearance but they do not (or should not) define what we are.
Some people have old cars that cost them relatively nothing yet they spend all their time and efforts on looking after them. Other people spend tens of thousands of pounds on flash expensive cars that they abuse and don’t look after. The same with houses. The same with bodies.
