Simple age converter

I want you to pick my code apart and give me some feedback on how I could make it better or more simple. In my opinion this is the best code I have written, being that I'm new to programming. The program is a basic "converter" that has the user input his/her age and it tells how many days, hours, and minutes the user has been alive. Let me know what you think!

import time
import sys

def name():
    name = input("What is your name? ")
    while name.isdigit():
        print("Make sure to enter an actual name.")
        name = input("What is your name? ")
    return name

def user_input():
    while True:
        age = input("What is your age? ")
        try:
            return int(age)
            break
        except ValueError:
            try:
                return float(age)
                break
            except ValueError:
                print("Make sure to enter a real age.")

def again():
    while True:
        again = input("Play again? Yes/No ").lower()
        if again == "no":
            sys.exit(0)
        elif again == "yes":
            break
        else:
            print("That was not an option.")

while True:
    the_name = name()
    age = user_input()
    Days = age * 365
    Hours = Days * 24
    Minutes = Hours * 60
    print("Ok {}, I have your results.".format(the_name))
    time.sleep(2)
    print("If you are {} years of age....".format(age))
    time.sleep(2)
    print("You are {} days old.".format(Days))
    time.sleep(2)
    print("You are {} hours old.".format(Hours))
    time.sleep(2)
    print("You are {} minutes old!".format(Minutes))

    again()

NOTE: If you make a change, please explain to me why and how it works in the most simple way you can, so I understand it better.

This:

def name():
    name = input("What is your name? ")
    while name.isdigit():
        print("Make sure to enter an actual name.")
        name = input("What is your name? ")
    return name

means that "1" is not a real name, but "a" and "17xy" are. I think it might be better to use some kind of a regular expression, or - better - just accept whatever nonempty string the user chooses to give you as his/her name.

In your user_input(), you try to convert the input to int, and - if that fails - to float. Why not straight to float? I don't see how is 17 better than 17.0.

Also, in the same function, your break statements will never execute, as the return statement terminates the function.

I think it'd be a much better program if the input was date of birth. Do you know your current age, as anything more precise than "between x and x+1 years old"?
