Formula To Calculate Age and Age at Death If Applicable

[WYNFRM]

F12:
DOB

G12:
=DATEDIF(F12,TODAY(),ʺYʺ) & ʺ Years, ʺ & DATEDIF(F12,TODAY(),ʺYMʺ) & ʺ Months, ʺ & DATEDIF(F12,TODAY(),ʺMDʺ) & ʺ Daysʺ

K12:
Death Date

L12:
(Age at Death)
=DATEDIF(F12,K12(),ʺYʺ) & ʺ Years, ʺ & DATEDIF(F12,K12(),ʺYMʺ) & ʺ Months, ʺ & DATEDIF(F12,K12(),ʺMDʺ) & ʺ Daysʺ

I am having trouble with formula for L12-current gives me parse error. Also, would it be possible to alter G12 to displayed 'Deceased' instead of continuing to age if there is a date in K12? And on that same token, could L12 display 'Alive' if no date is entered in K12?

Excel uses straight quotes:

	F	K	L	M
12	2/4/1963	5/10/2017	54 Years, 3 Months, 6 Days	L12: =DATEDIF(F12, K12, "Y") & " Years, " & DATEDIF(F12, K12, "YM") & " Months, " & DATEDIF(F12, K12, "MD") & " Days"
