a lot of people wish for their childhood, wish to go back to their past, when things were "simple" or "different".
fine, so you're getting older. you feel time is slipping by. your body and mind can't do what they could before. but that's because they did what they were meant to!
there's nothing wrong with losing control of your body with old age. because you should have gained enough in your mind now, to realize what matters.
I so agree with your reasoning, & I think it's rare. I do wish for simpler times, for times from long before I was born even. I know that the today I have is blessed, but I think that's one flaw of most humans (including me), we can only see the true value of things in hindsight. Something like the Benjamin Button effect.
But I am slowly trying to live more consciously in the present, despite all the silly setbacks I've had recently I know life is good & I am happy.
