I have this so far, but when I check people after it doesn't alter the age keys values to prepend "$".I want to assume I dont know which values are of type of number, so I want to do a check and change it to have $23, $3, $8 etc.

```
const people = [
    {name: 'John', age: 23, sex: "male"}, 
    {name: 'Andrew', age: 3, sex: "male"}, 
    {name: 'Peter', age: 8, sex: "male"}, 
    {name: 'Hanna', age: 14, sex: "male"}, 
    {name: 'Adam', age: 37, sex: "male"}];

let indVals;

people.forEach(function(arr) {
    indVals = Object.values(arr);
    console.log('Individual values: ',indVals);
    for(let val of indVals) {
        if ( typeof val === "number") {
            val = "$" + val;
        }
    }
});

```
