Here's another thing I observed..
1. Khaleda Zia went to Saudi Arab for her leg treatment.
2. Sheikh hasina went to USA for her ear treatment.
3. Manna Bhuyian went to singapore for engiogram.
4. Abdul Jalil went to singapore for heart treatment.
5. Saber hossain chowdhury went to bangkok to recover from the pollice beating.
6. President Iazuddin went to singapore after suffering from heart attack.
These people are/were placed in the highest positions of the government. Awami league served one term and BNP is going to finish it's second term. But they themselves don't have faith on the medical facility of the country. Reminds me of a joke :
"A person went to have lunch on a restaurent and find the food was not good at all. So he asked the waiter to call the manager. Then the waiter replied 'Sorry sir, manager went to lunch!'"
I'll finish now with two links. First, I never knew that "Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo." is a grammatically valid sentence. It actually is and have used as an example of how homonyms and homophones can be used to create complicated constructs. Check this out here at wikipedia and the second link's also from wikipedia a collection of very funny mathematical jokes. Check them here. Have fun!
