Inner Core Still Intact

Every day I wake up with my inner core still intact, And that is an established fact, So, I seldom worry about that, Even when I take off my hat, Or decide to pick up a bat. I don't know what makes it so, I only know it can take quite a blow, Though the outer core may start to glow, And burn marks start to show My inner core is still good to go. It is still a mystery to me, Why others cannot say the same, And find it hard to stay in the game, Which is I think is quite a shame. Contact with friends helps strengthen my inner core Of this I am sure, A joke or two seems to please it some more, The right food to the fore, Helps the core, To do more, A good night's sleep reduces the chances of stress on the core, And although children are quite a chore, They tell us when we are in danger of becoming a bore, And we need to go out the door, To learn once more to explore, To Lower the temperature in the inner core. Every day I awake with my inner core still intact, I know I must have shown some tact, Failed to overreact, And others did not decide how I should act. Though every day I give thanks that my inner core is intact, And I am glad to do that, There is one thing I don't know for a fact, Does it live under my hat? Or if I take off my shirt, Will I find it resides inside my heart?
