Chin Behaviour Changes with Age?

My female chinchilla is getting older (obviously, that's usually what happens.. ha) she's not old-old, she's about 6 or 7 years old, but I feel like she is getting a bit nicer towards me with age? Whenever I put my hand near her, not on her, but near her, she would push me away with her paws. Now, she comes over to my hand and grooms/licks my fingers and palm, and sometimes even climbs onto my hand! This might not seem like a big deal to some chin owners, but my chinchilla doesn't really like contact, she's not aggressive or anything, but I respect who she is and don't push her to become any different.



I haven't done anything differently recently, still treat her the same, just curious as to whether this has happened to anyone else or if it is common for chinchillas to become more relaxed as they get older. Thanks!
