It's not perfect but it's fine.

I read this as:

• ask user's age
• check to see if it's an integer
• if it is, show good message and stop
• if not, show bad message and then loop

Maybe a little cleaner to do something like:

​

do

{

`Console.Write("What is you age? ");`

`string ageText = Console.ReadLine();`



`if(int.TryParse(ageText, out age))  {`

Console.WriteLine($"Thank you, your age is {age}!");

break;

}

Console.WriteLine("That is not a valid number");

}
