# Just take something from the last subset

Does there exist an infinite family of non-empty sets $$A_i$$ with $$A_1=[0,1]$$ (i.e all the number between 0 and 1 inclusive) which satisfies

$$A_n \subseteq A_{n-1}$$

such that there doesn't exist $$X$$ which is in all of the subsets, i.e $$\forall x \in \mathbb{R}, \exists \space n \space s.t \space x \space \notin A_n$$?
