What is the healthiest longest living cat breed?

[KaraLani]

I had to put my cat down, she was my best friend and she was so sick and in so much pain. I got her when i was 10 and now that she is gone, i have never felt so alone in my life. I had a red tabby female which the vet say is rare. and she also said red tabbys are known to have a certain heart problem, and thats what my kitty had, and some other bad things too. I thought she would be my buddy for a really long good 18 years or something like that. Some people told me to adopt another cat and start over, but i dont know yet. If i were to adopt another cat, i want to know what im doing. So what is the longest living and healthy cat that you know of? I was reading online that Burmese cats are pretty healthy but i want to know your opinion. Thank you. And again i probably wont be adopting anytime soon, its to early for that
