Luca:
Luca is welcome to break bread with me anytime. Or I guess from your perspective break a leg, (or two or arm.) Oh sleeping with the fishes! I guess he doesn't want to eat.
In most ancient societies and modern non-American ones, age is equated with wisdom. The wisdom you impart as Obie-Wan far exceeds your 14 years of earth age, thus the attempt to keep bumping you older.
As long as you outlast the affects of aging on the mind, you'll have to be twenty years older than you are.
And I must admit I post all of the above out of fear of a visit from Luca, or Anthony or the crew, but most especially from Vito. Oh, that's right. He's dead.
