That is partly assumable - especially since more people are smokers than ever before. However, our average lifespans have also dramatically increased in the mid 20th century mostly due to increased hygiene and antibiotics: 18th & 19th c. around 35 y, early 20th c. up to 45 y, late 20 th c. going up to 65 y. (worldwide). And lung cancer regularly shows rather late (beyond 45 y, definitely).
