Neon can last decades. In practical terms the normal expected life span is between 8 to 15 years. Neon can be repaired and recharged as long as the tubing is not cracked/broken.
I had tubes last an entire season which for me is around 2000 miles. I always start the new season with new tubes. I just don't trust them after sitting all winter. I also check my tire pressure before every ride which helps a lot.
