You are long-lived.
Prerequisite: Inner Strength, Talented, mortal creature type.
Benefit: Add one-half the maximum result of your race's maximum age modifier to your normal middle age, old, and venerable age categories. For example, a human who took this feat would add 20 years to the three milestones, making them 55, 73, and 90 respectively. You calculate your maximum age using the new venerable number. This feat doesn't lower your current age category.
