        int year = sc.nextInt();
        System.out.println("insert Month of birth? >>>");
        int month = sc.nextInt();
        System.out.println("Insert Day of birth? >>>");
        int day = sc.nextInt();
         
        LocalDate cur = LocalDate.now();
        LocalDate brn = LocalDate.of(year, month, day);
        long years = ChronoUnit.YEARS.between(brn, cur);
         
        System.out.printf("User is %d years old", years);
