If they remain injury free and still keep getting to the finals of tournaments, I don’t see why they should retire. Earning more money is a powerful incentive.
MD can usually retire at a later age, so if they stay injury free, its possible. I am wondering though if SYQ is trying for Olympics in 2028, saw on Chinese media, his dad said he has decided to play for a few more years. Not sure what how many few means.
I think you could start a thread on MAS Open 2025 in 2024 tournaments and later admin/moderator can move to 2025 when it is available.
