Generally you are correct. Most tennis players are burned out by the time they are hitting their mid-thirties. So its still amazing to see her keeping up with the younglings. If you have noticed Venus is the one who hasn't really been winning much in the laat year or two. The age has worked on her. Her knees and ankles are shredded by now.
I guarantee you will hear you her retirement by the end of the year.
why should we not be excited when serena is defying odds and still dominating 16 years since her first grand slam win, when no one seems even close to upsetting her reign, when she has surpassed former greats and shown that you can still compete past 30 years? if she finds the motivation to continue she will still win past 35.
She's exceptional. She will soon break Steffi Graf's 22 career slams record. Kwanza Shara-moans ni customer kwake. Though, I feel the game needs more young competitors to give the veterans a run for their money.
