I don't even know man, I hate this question so much.

For audio, there was already an assumption that 120TB could hold 21.6 years of audio. I doubled it and found out that 47 years of audio would take up 256TB. I already thought that was a bit too much, but after trying to manually calculate it myself using videos I've found online, I've been coming up with even higher numbers than usual.

Actually, upon further notice. I was calculating incorrectly. My bad.

I may just go with what I was attempting beforehand. Calculating how much space is on a CD, and multiplying that by 47 years.
Especially low when you add in the extra information beyond sight and sound. If you were to account for the other three legitimate senses (no ESP for you, my friend) that complicates matters even more.
You've removed sleeping time because you feel it's not recording, but it is loading information, reviewing it, editing it, and copying it. Everything you did in the day is repeated and jumbled with new copies during your dreaming time, so without running a disk cleanup you'll have tons of extra data in there.

So, like Seriously said, just HD footage and audio accounts for about 500MB per hour. If you add in sensory information of touch, smell, and taste...lets assume they all three only account for the same size as sight or sound. That still makes it 750MB per hour.

Now are you also accounting for background processes, such as system analytics and programs running the whole system like an actual computer would have? How much RAM, alone, does breathing require?

Title for your paper : "You life on CD; a sufficient amount of discs to make a fabulous sequin dress ?"
Honestly, the question just wanted sound and sight. It wanted it for 70 years but made apparent that "one third is spent sleeping" so I'm assuming it wants me to factor in that into the calculations.

Looking at some stuff online, I've worked out that audio being recorded at a sample rate similar to CD's would be around 261TB of data. Which isn't a bad assumption. I already estimated using other data that it would be 264TB and this was an overestimate. So I think that's right.

As for the video. I must be messing up the calculations again. I think I've got the right idea but something isn't going right.

You only know there is 1 million pixels on the screen, 3 bytes per pixel and the video is recorded in 30fps. And there are two cameras, meaning the result is doubled. You're somehow supposed to come up with how much time 47 years would take up.

I'm getting around 16283TB's. So I already know that's wrong.

If anyone could help me out here, I'd be really grateful. It's already 4am.

I'm no expert on audio-visual recording, but here goes :

70 years of data.
VIDEO - 1 megapixel screen (720p is 921k pixels so I'll work on that, because no-one has a 1000x1000 screen, though you could argue that 1080i switches between two 1-megapixel frames). 5 megabits/second = 0.625 megabytes/second.
Stereoscopic recording doubles that input (we'll ignore overlap, as both images are used by the visual cortex to create a 3D image) so Video = 1.25MB/second
AUDIO - 256 kbits/second for the audio = 0.032 megabytes/second. We have two ears, double the audio input. Therefore - Audio = 0.064MB/second

Per day = (86400*1.25)+(86400*0.064) = 108,000+5529.60 = 113,529.60MB
Per four calendar years (to compute leap years) = 165,686,745.60MB 
Four years fit into 68 17 times. So 165,686,745.60*17 = 2,816,674,675.20MB.
Add two more standard years to reach 70, and you get 2,816,674,675.20+(41438304*2) = 2,899,551,283.20MB

2,899,551,283.20MB = 2,899,551.28GB = 2,899.55TB of data.
For 47 years of data, you get 1,946.84TB of data.

Don't take that as kosher, it's what I could scribble down before going to work. 
It doesn't take into account compression (the 5mbps [1.25MBps] standard I used leads to 9Gigabytes for a 2-hour film). For example, compression akin to a 1GB file for a 2-hour film would divide the final figure roughly by 9 (322TB for 70 years, 216TB for 47 years).
It also doesn't take into account variable bit-rate. For example, you could argue that pure black input, during the sleeping periods, creates more or less data (based on whether a black pixel means more data storage than a white one). That might be too picky.
Thanks man, with your calculations I'm feeling better about mine. We got similar numbers (and thanks for reminding me 1 megapixel is 720p, not 1 million pixels.)

You don't need to count the audio into the video equation though. That's calculated beforehand and added onto it.

I think the final answer I got was correct.
St Patrick's Day is coming up, and as usual I'll dress up in Orange, Green and White apparel. Something I've been doing for the past 13 years or so of my life.

So I ask my mother where to find my Orange Jacket, and Green and White sleeved shirt and she starts having a go at me saying stuff like "You suuuuuuure you wanna do this?" and "Aren't you embarrassed, some people are embarrassed to show their pride"

Confused, I just say "Why would I ask you where these things are if I didn't want to dress up on this day?" and she still keeps on going on about how I might be ashamed of doing this, and how I should be proud of my heritage and stuff.

I don't even know anymore.

She's going to do the same next year as well.
If you travel three states away for work for five weeks and a good bit of your work will be outside, pack a coat. It's a good idea.
On a TOTALLY unrelated side note, I've been oddly cold the past few days.
I need to stop buying Cookie's from the store on campus.

They're always hard and I never like them.

I have two bags right next to me.
Downloaded iOS 9.3 on my iPad, and it has a screen tint feature so that it doesn't hurt your eyes at night. Happier nighttime browsing !

I don't know why I'm so excited about this, but damn is it going to be useful :)

My wife's Galaxy S6 has a feature that changes the tint on the screen at the same time every evening for that reason. She really seems to like it. Good find for your iPad, Seriously.
You can get a program that does the same thing for computers called Flux. Its nice and customizable, but the default works just fine for me.

I love flux. I set my location further east than where I am, as I like it to kick in quite a bit earlier than official sunset.
You want to know what Irony is? Irony is being a guy who is in the middle of writing a book about Japanese Poetry and finding out that today is World Poetry Day on twitter at 10:00pm.
Slammed out a couple Tanka and hit a YouTube celeb with a Renga to compliment his Haiku. Take that twitter poets.
So, it turned out I had two instances of Steam on my computer. One from 2 years ago when I did a fresh install on my computer and put all the data from the old hard drive onto the new one, and the current version of steam I use.

This meant that I've had 161GB of useless information taking up my computer for no real reason. Most of it being installed games I didn't even know where installed.

Good thing I did a check, it's deleting it all now.
