The ten's digit of my age is seven less than three times the one's digit of my age.
Hate me yet? How about this one: a train leaves New York heading to LA at 35 mph. A second train leaves LA heading to New York at 34.739130434782608695652173913043 mph but starts one day later. Assuming there are 2,444 miles of track between the two and no stops or slowdowns, the hours passed since the train left New York till the trains collide is my age in years (rounded down).
