Eggsy's second chance (kingsman)

Gary "eggsy" unwin was a kingsman, he had been for decades now. He has made friends, lost friends, saved the world (multiple times) and learnt new skills on the way.

Only lately things went wrong in eggsys life, where he doesn't feel the need to keep fighting, so when on a mission eggsy sacrifices himself.

Only to his shock he wakes up as a child again, the day Harry gives him the medal that will change his life.

What will eggsy do with his second chance in life?
