So, is this person not going to go to a concert this year, or to a party... unless they're willing to go with <5 hours of sleep that night?

That's the deal. I'm not much of a party person anyways. I do get to take a nap in the afternoon though, if I do that ;)

Nik, though I do that already and going to do that in the future also,this, however, is an awesome read. I am not any kind of person - morning or night. I work well in both cases. But I like to get up early every morning. It gives me 14 more hours every week than people who wake up at 7 and 28 more hours than people who wake up at 9. So in the whole year, I will have 2*365/24=30.4 more days to work on me or the things that I love than a person who wake up at 7 and 60.8 more days than the one who wakes up at 9.

That's is crazy. Isn't it?

I love how you used the math to figure out you have an entire month more, that's definitely sick! Thanks for sharing :)

Well if they go to bed 2 to 4 hours later than you do, then you have 0 more hours a week, and 0 more days a year than they do.

While mathematically correct, this only holds true if they are exactly as productive from say 12 pm to 2 am after a long day as they are from 5 am to 7 am after just waking up.

Possible? Yes.

Likely? No.

Why stop here? you can stop chewing your food and only drink it, it will save you time :p

Numbers are nice but the repercussions of the lack of sleepiness and the direct effect on your productivity can lead you to a serious depression.

Where did the author say he or she is going to bed late? I go to bed at 9 pm, it's a matter of priorities.
