1 has been hit hard by injuries in recent campaigns, undergoing multiple hip operations and another procedure to mend a foot, so it's not the silliest question.
Hewitt perennially replies that he still thinks he can compete with the best players in the world when healthy -- or close to it.
The feisty baseliner proved it Sunday when he beat his fellow 32-year-old, Roger Federer, 6-1 4-6 6-3 to win the Brisbane International.
It was Hewitt's first title since downing Federer in Halle in 2010 and his first in Australia since Sydney nine years ago.
The victory over the 17-time grand slam champion won't be enough to earn Hewitt a seeding at the Australian Open next week but once again he'll be a player the favorites want to avoid in the early rounds.
