Lactose-Free and Nondairy Options. Dairy products are high in calcium, protein, and other nutrients. You may still be able to get these nutrients from dairy if you're lactose intolerant. 1  On average, most lactose-intolerant people can tolerate about 1 cup (8 ounces) of milk, says David Goldstein, MD, a gastroenterologist in Emerson, N.J.
The large tortoises from the Galapagus Islands can live more than 200 years. Some American box turtle have been documented at over 100 years old. Some sea turtles probably live 75 years or more.
The survivorship curve of box turtles is therefore probably similar to that of other long-living turtles. The average life span of adult box turtles is 50 years, while a significant portion lives over 100 years. The age of a growing box turtle in the wild can be roughly estimated by counting the growth rings on the scutes; the plastron is the best place to do this because it also allows examination of wear pattern.
