1 Rejoinder We greatly appreciate the commentary and positive feedback of discussants Prof. Jialiang Li and Dr. Rhythm Grover to enrich our paper and its context.

Abstract Total mesorectal excision (TME) remains the primary recommended treatment for high-risk T1 and T2 rectal cancer.

Allocating investments through time to satisfy income during retirement is not the same as maximizing wealth at the date of retirement. Some fund managers portray the maximum wealth objective as a proxy that satisfies the retirement income objective, and use ‘glide paths’ to manage portfolio risk. But this approach ignores the risk of income sufficiency, especially for healthy retirees living beyond life expectancy.
