You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: main.go
    path of file: ./repos/training/example05-interface/example02
    
    the code of the file until where you have to start completion: package main

import "fmt"

type Human struct {
	name string
	age  int
}

func (h Human) Say() {
	fmt.Printf("I can say, I am %s, %d years old\n", h.name, h.age)
}

func (h Human) Run() {
	fmt.Print
    
func main() {
	tom := Singer{
		Human:     Human{"Tom", 22},
		collecton: "learn golang",
	}
	peter := Student{
		Human:  Human{"Perter", 18},
		lesson: "learn php",
	}
	jerrk := Human{"jerrk", 26}

	var men Men
	// men å­˜ tom
	men = tom
	men.Say()
	men.Run()

	men = peter
	men.Say()
	men.Run()

	men = jerrk
	men.Say()
	men.Run()

	x := make([]Men, 3)
	x[0], x[1], x[2] = tom, peter, jerrk

	for _, value := range x {
		value.Say()
		value.Run()
	}
}
