Jonny May expects his England career to end after the Rugby World Cup, so he wants to bow out in a blaze of glory.
The 33-year-old has branded this tournament in France "bonus time" on a Test career that has already spanned 75 caps, 11 years and three World Cups.
He has resolved to leave everything on the field in the quest for World Cup glory.
"This will be my last World Cup and most likely my last time playing for England," said May. "I'm incredibly grateful to be here. I told Steve Borthwick in January, I'm all in. That's the sort of guy I am.
"I'm still as fast as ever but I'm realistic to know that I probably only have a couple more years to keep that going.
So I've just got to rip in and give everything I can for this last period of time. I am definitely on bonus time; this is my 11th year with England now. But a serious time as well, because we've got an opportunity to win a World Cup, and I want to do my country proud."
England have already qualified for the quarter-finals, where Wales or Fiji lie in wait, but they are still at full strength to take on Samoa.
George Ford and Owen Farrell will start at 10 and 12 together for the 41st time in England colours in tomorrow's Pool D clash.
May scored twice in a 28-9 win over Samoa in November 2014 — the first time Ford and Farrell combined in England's midfield.
"They haven't changed much really, in some ways," said May, of England's vastly experienced playmakers. "Of course they've improved as time's gone on, but they were as wise and as knowledgeable then as they are now.
"We enjoy taking the field with each other, we've been through a lot. They are both very close friends of mine. Include Marcus Smith as well, and I don't think any other team has three 10s of that quality."
