1.slide!
Hi guys! Today I am gonna talk to you about cave diving. I chose
that extreme sport because my father said that this could be
intresting, educational and fun. I agree with that. So lets begin .!

Cave diving is diving in water caves. !
In UK it is called just caving and in US it is called scuba diving.
They are not same but the point is same and so the technique. !
Basically cave divers swim and explore there .!
Sometimes they also find fish , animal and human bones. And they
give these to museums.!
The first cave diver in world was Jacques -Yves Cousteau and he
dived at Aqua- Lung in 1943.!

There are so many hazards that can be there. !
First is example get lost in caves. In underground is everything so
similarity. Thats why you need guide line (I´ll tell you later what it is
exatly). You can´t remember what way did you come or where did
you turn right and when left.!
Of course , when you dive too deep , you maybe get stucked or
your air may run out. So you drown. !
In caves there are in- and outflowing water currents and when
they are in no propostion they can be bad for divers. And they may
collapse.!
You get decommpression sickness if you come too quickly on
surface. Your blood is gonna boil and you will die. !

follow way back .!

· And when you begin to miss me, dont forget it was you who let me go. · There is an end to things no matter how much we want to hold into them. · Otsisin keset seda pimedust, sind ja loodetud vabadust,kui mu käed su poole, tegid alguse loole, printsessist ja printsist, ühest kaunist kandist, kus oleme meie kaks, kus lõbutseme, kuni otsas jaks. Sa ei pea muinasmaad looma, sa ei pea tähti taevast tooma. Ole vaid minu kõrval, kui tõuseb päike. Ole vaid mu kõrval kui mind piinab meeleheide. Ole mu kõrval, kui kumab kuu, kui su nime hüüab mu suu, ära tõota mulle, et armastad mind, kui ei ole valmis ohverdama end. Luba, et printsess jääb printsiga, kuni nad veel siin ilmas elavad. Unustame hetkeks kõik muu me, tunnetame üksteise kiireid südamelööke, kas tunned, kuidas süda jätab lööke vahele, see kõik on midagi uut, meile kahele. · Women are stronger than men, because they can walk in a 12 cm stilettos without showing t

Tallinn´s University Pedagogical College Department of Youth Work and Continuing Education Andra Pant NT-32 GETTING PHYSICAL Tallinn 2012 "Delivery is more important than content." Arch Lustberg, speech trainer According to wellknown social anthropologist Edward T. Hall, 60% of our communication is nonverbal. That means whenever we stand before an audience, our stance, our posture, our facial expressions, our hand gestures, our whole body dynamic communicate more than our actual spoken words. A stiff, immobile speaker is often a boring and usually ineffective speaker as. It is therefore essential to know how to be ph
THE CAPITALIST NIGER Chika Onyeani ………………………Every African must internalise this book - period….DAA INTRODUCTION In October 1960, Nigeria received its independence from Britain. By then, Ghana the former Gold Coast had been independent for three years under the great Osagyefo Kwame Nkumah. It was a time for celebrating Africa’s coming of age, as more and more African countries received their independence either from Britain or France. It was especially a poignant time for Africa, as then British Prime Minister Harold McMillan articulated his now famous “winds of change” sweeping Africa. We had high hopes for Africa, for the Black race, that the insidious imposition of foreign rule on us, the looting of Africa’s natural resources by our colonial masters accorded us would be things of history. That is more than forty years ago. Unfortunately, the promise of independence has not been fulfilled. Today, Africa has become more desolate; there is more starvation
