Consider renaming your private variable to something like _age.

private string _myString;
public string MyString
{
  get { return _myString ; }
  set
  {
    if (value != null && value.Trim().Length > 30)
      value = value.Substring(0, 30);
    _myString = value;
  }
}

public class MyClass
{
  private string _myString = string.Empty;
  private int _myInt = 0;
  private bool _isDirty = false;

  public string MyString
  {
    get { return _myString ; } 
    set
    {
      if (_myString != value)
      {
        _myString = value;
        _isDirty = true;
      }
    }
  }

  public int MyInt
  {
    get { return _myInt; } 
    set
    {
      if (_myInt != value)
      {
        _myInt = value;
        _isDirty = true;
      }
    }
  }

  public bool IsDirty
  {
    get { return _isDirty; }
  }

  public void Save()
  {
    // Save the record to the database....
    // then reset the "dirty" flag.
    _isDirty = false;
  }
}
