Do you fear your own death coming closer day by day?

I dont want to sound morbid, but this thought has become more present in my mind since i became a Father, the thing is she is only 10 months old and i am 48, i am split up with her mother so my time with my daughter seems ever more valuable...., but i cant help thinking about the limited amount of quality years that i have left with her, it just all seems so sad, does anybody else have similar thoughts and how do you deal with them
