You are feeling like a child who never wants to grow up yet your aging body puts you in a dilemma, right ? It might be because we live mostly inside our minds and pay less attention to what is going on the outside, in our body or in our surroundings, our environment. If you notice carefully, although age is just a number, our mind is also growing with our body. In your case, the mind is not able to catch up with your body because maybe as you are growing old in your body, you have not expanded your mental consciousness. We can still play with dolls at the age of fifty or laugh like a child, but that does not mean that we cannot look at our environment, our bodies, with attention,love and care...for example, around our parents, we might be still behaving like little kids, but will you be terrified to see wrinkles in your mom's face ? and if yes, would you stop caring for her ? So, I think that love will fill the gaps if there are any...love yourself, take care of your body, wear nice clothes and after that when you look yourself in the mirror, smile at the mirror and say " I love you"- everyday.
