Todavía tengo casi todos mis dientes
I still have almost all of my original teeth
casi todos mis cabellos y poquísimas canas
I have almost all my hair and very little has turned silver
puedo hacer y deshacer el amor
I can still feel the thrills of love,
trepar una escalera de dos en dos
I can climb the stairs two steps at a time
y correr cuarenta metros detrás del ómnibus
and I can run forty yards behind the bus...
o sea que no debería sentirme viejo
so, I shouldn't feel old
pero el grave problema es que antes
but the serious problem is that before, in my youth
no me fijaba en estos detalles.
I didn't pay attention to all these details.
