My solution...

I opted to access the DOM (covered in the previous course) rather than the console. I also found the method toLocaleString() to make the number prettier. 

// Access the DOM
const main = document.querySelector('main');

const secondsPerMin = 60;
const minsPerHour = 60;
const hoursPerDay = 24;
const daysPerWeek = 7;
const weeksPerYear = 52;

// My age in years. (So far.)
const yearsAlive = 53;

let secondsPerDay = secondsPerMin * minsPerHour * hoursPerDay;

// secondsAlive does not count the current year or account for leap years

let secondsAlive = secondsPerDay * daysPerWeek * weeksPerYear * yearsAlive;

// The toLocaleString() method formats numbers with comma separators

main.innerHTML = `
  <h2>There are ${secondsPerDay.toLocaleString()} seconds in a day.</h2>
  <h2>I've been alive for more than ${secondsAlive.toLocaleString()} seconds.</h2>
  `;
