It says it all that the pull of Usain Bolt is still one of the major attractions at the Commonwealth Games.
The legendary sprinter retired last year in devastatingly disappointing circumstances, suffering a hamstring tear in the 4x100m relay at the World Championships in London.
However, just his presence in Gold Coast, Australia has been enough to attract plenty of attention.
While the Jamaican is merely a spectator these days, he has been attending plenty of events at the Games, including those of his former team-mates.
Yohan Blake and co. could only manage bronze in this year's relay, with England taking gold and South Africa silver.
Perhaps that result, or simply the buzz of being back at the track, prompted Bolt to send a couple of cryptic tweets.
Having only quit the sport eight months ago, the 31-year-old posted to hint he had retired too early:
"Did I retire too soon? Hmmm," he wrote, before adding: "Watching the relay just now made me ask myself a few questions. Anyhow #TeamJamaica all day everyday #GoldCoast2018 #CommonwealthGames."
Fans have responded
It's easy to see why the tweets have got fans excited, with many now believing a comeback could be on the cards:
There will always be those who think the veteran ought not to return as he would risk putting a dampener on the incredible memories of his career - but just imagine Bolt at Japan 2020. Maybe it's not completely out of the question.
At the 2000 Sydney Olympics, American Michael Johnson became the oldest short-distance gold medallist at the age of 33 and also won gold in the 4x400m relay, though the US were later stripped of that accolade.
So, it's perfectly possible that there is still enough life in Bolt to compete.
Bolt has been training with Dortmund
Indeed, he clearly still has what it takes to keep up with elite sportsmen, as he has been training with Borussia Dortmund and even did enough to earn a three-week trial to fulfil his dream of becoming a professional footballer.
Only a matter of days ago, Bolt alluded to having plans in football.
“Everyone feels like I’m just kidding around – [that] I’m joking," he said, per Bundesliga.com.
"But I’m serious. I’m actually going back to Dortmund in a couple of weeks to work with them for three more weeks just to assess myself at a better level - to see what level I’m at or what I need to do, or if I can.
“So that’s something I’m focused on doing and I’m looking forward to the challenge because that’s what I want. I want a new challenge in life and that’s my focus."
His latest tweets seem to contradict that, but you get the feeling something big is going to happen from Bolt either way in the coming months.
