About print out the seconds i've been alive.

var secondPerMin = 60; var minPerHour = 60; var hourPerDay = 24; var dayPerWeek = 7; var weekPerYear= 52; var secondPerDay = secondPerMin * minPerHour * hourPerDay; document.write('There are ' + secondPerDay + ' seconds in a day.');

var yearsAlive = 29; var x = yearsAlive * weekPerYear * dayPerWeek * secondPerDay; document.write('I have been alive more than ' x ' seconds!' );

Why it doesn't go through? Thanks!

I think you are missing something. You have two options how to join string with variables. The first is as you did document.write('There are ' + secondPerDay + ' seconds in a day.'); and the second document.write(`There are ${secondPerDay} seconds in a day. `);

var yearsAlive = 29; 
var x = yearsAlive * weekPerYear * dayPerWeek * secondPerDay;
document.write('I have been alive more than ' + x + ' seconds!' );

You just forgot to concatenate the text and the variable in your document.write() statement. Remember, any time you wanna stick stuff together in a string you've gotta use + to connect them.
