Human lifespan hasn't increased very much. Life expectancy at birth has increased significantly due to reductions in childhood disease and accidental death, but life expectancy at 50 and 60 have barely moved over the last 100 years. People have a much higher chance of making it to old age, but all the issues you cited will still hit them once they get there.
