The 39-year-old "Mad Max: Fury Road" actress will celebrate her birthday next month and revealed she's excited to hit the milestone because she's convinced people in their 40s are much better at enjoying life than youngsters, reported E! online.
"I'm so happy to be in my 40s and not be in my 20s and worried if I fit into my skinny jeans or whether I will be able to get into that club," Theron said.
"It's so nice to just be in love with your couch and make cheesy sandwiches and just enjoy life. It's been great."
