Flamboyant old bustards keep showing off
Among outrageously flirtatious birds called houbara bustards, old males may pay a penalty for years of extreme display.

Dangerous Times: Guppies don’t follow rules for old age
A study of wild guppies suggests that life in a dangerous place does not automatically push evolution toward rapid aging as previously thought.
