AsThe Big Bang Theoryenters season 10, the focus has turned to the shows future.
For series star Kaley Cuoco, the question of an eleventh season comes down to one thing: money.
Its a very expensive question for a lot of people, said Cuoco onJimmy Kimmel LiveMonday.

After Kimmel asked if she thought 10 seasons was enough, Cuoco nodded and said yes with a laugh.
Its a lot of hair.
I went from like hot to like 30 [years old].
She added: I just cannot believe how much we have all changed.
The guys look exactly the same.
Im the only one thats changed.
Theyve worn the same t-shirts this entire time.
Well put it on as long as everyone wantsBig Bangon the air.
I hope it lasts forever.
