I would love, love, love to swap bodies with Marco for a day. I would spend that day in bed spooning him, so that he could feel how good it is to be spooned by his bigger-than-me self. My manly arms would envelope his smaller frame, and he could feel just how wonderful it is to be the smaller ‘half’ of this perfect fit arrangement. I’m sure it feels good to be the bigger ‘half’ too. When I spoon him I don’t fir properly. If our heads are close I’m half way up his back and he doesn’t tuck neatly in my front. If we tuck ourselves in neatly, my head is half way down his back. Not ideal!
Swapping bodies with someone is all fair and well, you can live their life to a certain degree and perform their daily tasks. After this I still don’t think you would understand how it feels to be them, as you’ve not truly lived a day in their shoes. For example, a lot of my life happens in my head.
I react to various stimuli throughout the day, and my own self, ME, interprets these stimuli completely differently from other people. Our past experiences may influence how we react and feel. As well as our current situation. No one can walk my path, and I can’t walk it for someone else. I can empathise with situations and relate to stories and events, but at the end of the day we are all as unique as every star in the universe, and regardless of whose body I am in I will always be me.
