This is my solution. Don't know if i got it right?

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 daysPerYear = 365; const yearsAlive = 35;

const secondsAlive = secondsPerDay * daysPerYear * yearsAlive; console.log(I have been alive for more than ${secondsAlive} seconds!);

I think the idea was to complete the calculation using only the variables created already in the video.

Hint: you defined "daysPerWeek " and "weeksPeryear" but have not used them yet.

Glad you pointed this out. I looked right past them. I also got different results with my idea vs the variables in the file.

If you ask 99% of everyone they will say there are 365 days in a non-leap year. So I rolled with that. 

const yearsAlive = 10;
const daysAlive = yearsAlive * 365;
const secondsAlive = daysAlive * secondsPerDay;

"Been alive for more than 315360000 seconds!"

Using the variables there are 364 days in the year. 

const secondsAlive = (secondsPerDay * (daysPerWeek * weeksPerYear)) * yearsAlive;

"Been alive for more than 314496000 seconds!"

I know we aren't looking for 100% precision in the project. But I thought it was novel and share worthy.

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

const yearsAlive = 23; const secondsAlive = secsPerMin * minsPerHour * hoursPerDay * daysPerWeek * weeksPerYear * yearsAlive; console.log(I've been alive for more than ${secondsAlive} seconds!);

This is what I got, and it isn't exactly correct but I'm just happy I made legitimate code!

const secsPerMin = 60; const minsPerHr = 60; const hrsPerDay = 24; const daysPerWeek = 7; const weeksPerYear = 52;

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

const yearsAlive = secsPerMin * minsPerHr * hrsPerDay * daysPerWeek * weeksPerYear * 31; console.log(Ive been alive for more than [974937600] seconds!);

We already defined 'secondsPerDay' earlier in the video, so I used that in my calculation:

const yearsAlive = 34; const secondsAlive = secondsPerDay * daysPerWeek * weeksPerYear * yearsAlive;

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

I've been alive for more than 1069286400 seconds!

const secondsPerDay = secsPerMin * minsPerHour * hoursPerDay;

console.log(`There are ${secondsPerDay} seconds in a day.`);

const yearsAlive = 34;
const secondsAlive = secondsPerDay * yearsAlive;

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

"I've been alive for more than 2937600 seconds."

This is what I got for this.

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 = 36; const secondsAlive = secondsPerDay * yearsAlive * daysPerWeek * weeksPerYear; console.log(I've been alive for more then ${secondsAlive} seconds.);

"there are 86400 seconds in a day." "I've been alive for more then 1132185600 seconds."

const secsPerMinute = 60;
const minPerHour = 60;
const hourPerDay= 24;
const dayPerWeek = 7;
const weekPerYear = 52;

const secsPerDay = secsPerMinute*minPerHour*hourPerDay;
console.log (`There are ${secsPerDay} seconds per day`);

const yearsAlive = 35;
console.log (`I've been alive for ${yearsAlive*secsPerDay*365} seconds.`);

I went a different way and did the calculation in the template literal. Worked like a charm.
