Ben bounces back from injury agony.
The Leicester scrum-half underwent surgery at the end of May after suffering a knee injury during a wrestling session with Tigers team-mate Toby Flood.
Youngs missed all three warm-up internationals but he returned to action off the bench against Argentina on Saturday - and turned the match in England's favour.
With England trailing 9-3 and unable to get a foothold in the game against the powerful Pumas, Youngs upped the tempo then scored the decisive try.
"It's nice to know that you can bring something different," said Youngs, whose running game has been such a key factor of England's style over the last year.
"It's been frustrating not playing. I just wanted to get out there, get my hands on the ball and just play some rugby, which I managed to do.
"We probably left it a little bit later than we would have liked but the important thing is we won.
"It doesn't matter if it's by one point or whatever, the winning is all that mattered.
"We knew it was going to be a tough game.
"A lot of people didn't realise how tough it was going to be. The belief this team has, we knew we'd keep battling to the end."
England will prepare for their next challenge, against Georgia's ferocious forwards, in Queenstown after flying to the adventure holiday resort for a change of scenery.
Some players have already been sampling the bungee swing and there are more adrenaline-fuelled activities planned for their day off today before the squad focus on tackling Georgia this Sunday.
The Georgians boast some of the most feared forwards in Europe and England need to be prepared for another war of attrition up front.
Davit Khinchagishvili is rated by England hooker Steve Thompson, a former team-mate at Brive, as the best loose-head prop he has ever played.
Georgia's tight-head Davit Kubriashvili has been keeping Carl Hayman out of the Toulon side.
England lock Courtney Lawes, meanwhile, has been cited for allegedly striking Argentina hooker Mario Ledesma with his knee, Rugby World Cup Ltd have announced.
Lawes will have to appear before a disciplinary in Auckland, to be chaired by independent judicial officer Terry Willis, from Australia.
The time and date of the hearing will be confirmed later today.
Lawes was cited by match disciplinary commissioner Murray Whyte for his challenge on Ledesma near the end of the first half.
England are to be warned by Rugby World Cup organisers to fix their peeling shirt numbers or face a potential fine. The white numbers, applied by a local company in New Zealand, failed to bond properly on the black jerseys and began to rub off on Saturday.
