I've always thought it would be interesting to track a group of juvenile wild Burmese and a similar group of captive Burmese to see what percentage of each group had the best chance of making it to adulthood. You would think on the outset that the captives would stand a better chance, what with no predators, a steady diet and constant care. But we know what happens to most captive baby Burms. They get abandoned, neglected, released into the wild, etc. I don't know if there's any realistic way of doing such a study (maybe with microchipping it might be somewhat possible), but I'm sure the results would be very interesting.
I had a 10 year old albino Burm that was as pampered as any snake in the country. Sadly, she died about 15 months ago due to an infection caused by eight impacted eggs. But it is rare to see captive snakes a decade old or older, much less one 30 or more years old.
I knew a dermatologist about an hour from my home who was a ratsnake enthusiast. He did have one python, though -- a ball python that was nearly 30. And that was eight years ago. Don't know if it's still alive or not.
