45 Life Lessons Written by a "90-Year-Old Woman"

People often tell Regina Brett how great she looks for her age. Turns out, she is actually 54 years old — not 90. She wrote down these life lessons the night before her 45th birthday after being diagnosed with breast cancer. Over that past decade, these lessons have gone viral on the Internet amid claims that she is 90 years old. Luckily, she finds humor in this misrepresentation, knowing how many lives she has touched.
