Is it strange to be 44 years of age and still be in love with dolls and doll houses. I dont play with them.?

i dont play with them but i really love them especially the Bratz dolls. and im trying to find the fisher price loving family doll house and put it alongside a 18 room miniture dollhouse i built some time ago.Im asking this question because as i get older my love for these things grow and i love to spend time adding to the different rooms. Ive been told that im trying to regress back to my childhood but i dont think so, considering i had a pretty nice childhood and i had a dollhouse then, but through this question i just wanted a different opinion.
