In Asia, a large tiger might sometimes kill and eat a small or medium-size panda or other Asian bear. Anywhere else in the world, the only animal that can eat a full-grown bear is another bear. But bears sometimes do eat other bears. Baby bears have the most to fear from other bears. Large male grizzly bearsâalso called brown bearsâoccasionally kill and eat grizzly bear cubs. And large male polar bears sometimes kill and eat small polar bears. In addition, sometimes grizzly bears kill black bears.

Benzodiazepines like Valium can stay in the system a pretty long time. It depends on how much you take and for how long. Also your health, age, weight and metabolic rate play a part. How long a drug stays in your system depends mainly on it's elimination half life. For Valium (diazepam) the initial distribution phase is followed by a prolonged terminal elimination phase (half-life up to 48 hours). The terminal elimination half-life of the active metabolite N-desmethyldiazepam is, on average, 100 hours.
