The evidence that the dodo bird (Raphus Cucullatus), extinct since 1681, could be alive is not quite as solid but still interesting. A night vision video recently uploaded to the Internet shows what appears to be a live dodo walking past an iguana.
Interestingly, hard-boiled eggs do not keep nearly as long as raw eggs, which can last three to five weeks in the refrigerator. There is a good reason for this. When a hen lays an egg, it puts a naturally protective coating on the outside of the shell.
Its easy to google and find information on the shelf life of hard-boiled eggs from seemingly authoritative sources. It seems roughly 1 week when refrigerated is the going shelf life I see quoted. Hard boiled eggs will keep for 4 days refrigerated in the shell, before they become unpalatable. 2  Soft boiled eggs(hard whites, creamy yolks) will keep in the shell, refrigerated for 2 days.
