Wow, a formula that can give my my age, and all I have to put in is my year of birth, and whether or not I've had a birthday this year.

There's nothing special about the formula though :rolleyes: ...but it works only for 2005 ... creeeeepyyy... :blushing:

I can just look at my drivers licence and find my age! And it works every year :tongue2:




that was pretty cool tho...

Actually, it works better next year ...... you get 6 pieces of chocolate on Sundays. :approve:

Look at what you're actually doing. (pieces of chocolate equals c)

You wind up with 2c+5.

Multiply by 50 to get 100c+250.

Add 1755 to get 100c + 2005 (alternative version - "What year was the University of Moscow founded? - add this to your result"; alternative two - "What year did John Adams start his diary?", etc.; alt 3 - "What year did Immanuel Kant suggest the solar system originated from a dust cloud?", etc; "What year was Lisbon destroyed by a giant earthquake and tsunami?", etc; or, more fun, "What was the birth year of Albert Cristoph Dies?", etc)

Subtracting your birthyear from 2005.

Unless you're over a hundred years old, this effectively shifts the chocolate to a safe location where it won't be affected while just subtracting your birth year from the current year.

To make it work next year, you either get more pieces of chocolate on Sundays or have to shift to 1756 (actually an improvement - 1756 was the first year St Patrick's Day was celebrated in New York, making this a very appropriate trick for a bunch of drunks at next year's St Patrick's Day party.)

Twenty-one years from now it will work even better, at least in the US - 1776 is a number that has more significance than 1755. People won't go "Huh?! :confused: " when you ask the modified version.

.... or else you really get to pig out on chocolate. :redface:
 
Yeah, that really ain't that amazing. It'll work next year too if you add 1 to the number that depends on whether you've had a birthday or not, cos you're just adding 1755 to 5 x 50 = 2005. Not creepy at all.
 
BobG, you're too fast for me!

Don't select, if you like saying "ooh !"

Let the number of times you want chocolate be 'n'

After step 3, you have 2n + 5, and after step 4, it's 50*(2n+5) = 100n + 250

Then you add 1754 or 1755 and get 100n + 2005 or 100n + 2004 (depending on when you had your last birthday)

From this you subtract your year of birth (yob), and have 100n + 2005 (or 2004) - yob

but clearly, 2005 (or 2004) - yob = your age, which is most likely a two digit number, 10x + y (where x,y < 10)

So, you are left with 100n + 10x + y

That last two digits of this are 10x + y which is your age, and the first digit is n, the number of cravings you have.

[/white]

This wont work if you are over 99 years old ! :frown:

it didn't work the first time because i typed the wrong number into the calculator!

did you figure this out, or did you find it.

I can guess your age too!

Think of your age
Add 17
Subtract 9
Subtract 8

Hey presto!

Not if you're retarded and can't follow the directions correctly. Then it tells you you only want chocolate 2 days a week and you're 97 years old. :yuck:
 
Artman trying to hide his age... tch! Give it up, old-timer.

Holy, cow! It predicts the future. When you're 97, you'll have problems with your teeth and won't be able to eat sweets, but you'll forget every three days. The 5 chocolates on Sundays are for the girls from the church that come to visit at the old folks home.

Edit: Oh, my bad - four of the girls just stand around outside smoking cigarettes and the only one that actually visits is Lydia, the daughter of Virginia and Ray. But, she's okay. She always asks about your relatives - why they never come to visit. She thinks you shouldn't leave them any money since they never visit you.

Then your family comes to visit, sprinkles a little water in your face and asks you how the pool was. Darn memory loss. :grumpy:

Yeah, that's for sure. Lydia could actually control the movement in her little toe. I could watch her count to 1,048,575 in binary on her fingers and toes for ...... well, days ...... at least until she'd pass out from dehydration. She once made it all the way up to 487,393.

Never put anything just for fun in here, you'll get ripped to shreds. :bugeye:

And it did accurately guess that I am 24 years old. :approve:

Eat way too much just before you start counting.

ditto. I ended up being 0 years old with 2 extra chocolates.
