Paper Summary

Corticosterone, a stress hormone, can help male lizards survive better. When given corticosterone, lizards ate more, moved more, and survived longer. This shows that corticosterone can improve survival by increasing energy use and activity levels. So, stress hormones like corticosterone might actually help animals live longer.
