I realize now I did it needlessly long (haha) but this is what I got:

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

const secondsPerDay = secPerMin * minsPerHour * hoursPerDay; console.log(There are ${secondsPerDay} seconds in a day);

const yearsAlive = 32 * secPerMin * minsPerHour * hoursPerDay * daysPerWeek * weeksPerYear; console.log(I've been alive for more than ${yearsAlive} seconds);

Yeah this might be better to just have as notes for yourself! You should also use days per year instead of relying on weeks, it is more accurate. If you want to be even more accurate you would have to see which year you were born and account for leap years.

You could also make a yearsToSeconds function:

function yearsToSeconds(years) { return years*365*24*60*60; }

const secondsAlive = yearsToSeconds(32);

console.log(I've been alive for more than ${secondsAlive} seconds)

Happy coding!

I feel super old. LOL!! Here's my version.

const secsPerMin = 60;
const minsPerHour = 60;
const hoursPerDay = 24;
const daysPerWeek = 7;
const weeksPerYear = 52;
const daysPerYear = 365;
const myAge = 47;

const secondsPerDay = secsPerMin * minsPerHour * hoursPerDay;
console.log(`There are ${secondsPerDay} seconds in a day.`);

const yearsAlive = secsPerMin * minsPerHour * hoursPerDay * daysPerYear * myAge;
console.log(`I've been alive for more than ${yearsAlive} seconds!`)

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

const yearsAlive = 99; // Your age const secsAlive = secondsPerDay * daysPerWeek * weeksPerYear * yearsAlive; console.log(I've been alive for more than ${secsAlive} seconds!);

This is what I came up with. I used previously declared variables in this exercise.

const secsPerMin = 60; const minsPerHour = 60; const hoursPerDay = 24; const daysPerWeek = 7; const weeksPerYear = 52; const yearsAlive = 26;

const secsPerDay = secsPerMin * minsPerHour * hoursPerDay; console.log (There are ${secsPerDay} seconds in a day.);

const secsAlive = (secsPerDay * 365) * yearsAlive; console.log(I've been alive for more than ${secsAlive} seconds!);

It looks like I did it right if I've been alive for 10006387200 seconds. haha

const secsPerMin = 60; const minsPerHour =60; const hoursPerDay = 24; const DaysPerWeek = 7; const weeksPerYear = 52;

const secondsPerDay = secsPerMin * minsPerHour * hoursPerDay console.log(There are ${secondsPerDay} seconds in a day. );

const yearsAlive = 32;

const secondsAlive = secsPerMin * minsPerHour * hoursPerDay * DaysPerWeek * weeksPerYear * yearsAlive

console.log (I've been alive for more than ${secondsAlive} seconds.);

Here's my version. 

const secsPerMin = 60;
const minPerHour = 60;
const hoursPerDay = 24;
const daysPerWeek = 7;
const weeksPerYear = 52;
const daysPerYear = 365;

const yearsAlive = 48;

const secsAlive = (secsPerMin * minPerHour * hoursPerDay * daysPerYear * yearsAlive)
console.log(`I've been alive for more than ${secsAlive} seconds!`);
