Shackman’s suggestion for the weekly Friday LBC post is a favourite topic among some people who are growing old physically but who claim that they are not growing up. I envy them. I wish that I could have stayed at my youth mentally.
Surely such talk or shall we say, wishful thinking is just that. One cannot really stop growing up any more than stop growing old. Degrees of such growth can be subject to discussion or observation, but we cannot completely stop either process.
We can certainly use the phrase as a whole with some tweakings for different contexts for humour but in reality, I am afraid that at least in my opinion, both processes are unstoppable.
