As redioactive material decays and the percentage of new material in the original sample increases, does the age of the sample substance increase, decrease, or remain the same?

Answer 1

The origin of the material stays the same, but of course, as time progresses (as the decay is happening, and as we breathe), all things get older.
EIther this is an odd question, or I am missing something. As I breathe, does my age increase? Of course.
