Fun, Puzzles, Travel
The following are a number of puzzles presented for your entertainment.
Feel free to submit any puzzles that you think are interesting,
my email address can be found here.
If appropriate I will include them here.
The main requirement for any puzzles listed here is they should not
require any advanced mathematical skills. If you find yourself
writing equations for any of the puzzles you are probably approaching
it the wrong way. (There are only a couple of exceptions below)
The puzzles below are approximately in order of increased difficulty
although it is only my own personal impression.
To answer your next question, no, answers are not provided
to most of the problems.
The whole point of a good puzzle is for it to prey on your mind
until you solve it.
If you are REALLY desperate I will reveal answers if you
beg or for a small inducement (eg: beer, chocolates, postcard).

Maybe in order to understand mankind, we have to look at the word
itself: "Mankind". Basically, it's made up of two separate words -

hundred and sixty-six."

standard representation of letters on computers) one gets the following,
