I reckon you only get old when you stop playing which is why I still look young (as far as I can tell I at least look like an adult now XD) and why J looks like a crotchety old man XD

Aside from the careless drop and the ensuing tantrum, sounds like you had fun putting it together :)
Being young at heart translates to the whole body. For me, the main ageing problems are my eyes and not healing as fast as I used to.
We had a great time and are now on to the next mission.
