Calculating age from date of birth and ignoring if blank

I've used the following formula to calculate a person's current age in years
based on a previously entered date of birth:

=ROUNDDOWN(YEARFRAC(P2, TODAY(), 1), 0)

However, if I haven't entered any data in the date of birth column, the
result cell shows the age "110", which throws out other calculations. Is
there any way to tell Excel not to enter any data if the date of birth is
blank?
Many thanks

Thank you, that's exactly what I needed/

As you may have guessed, I'm fairly new to this!
