Thrills and frights

<em>People are</em> strange creatures. They might take offence when you scare them accidently but they are willing to pay money to have a fright<em>, for example</em> at amusement parks. Why is <em>this?</em> Why do we enjoy being scared?
I think everybody just gets tired with <em>their</em> everyday grey routine at some point and <em>so</em> to get away from collected problems and emotional anxiety we choose to devote our weekend to a trip to <em>the</em> funfair. (We desperately strive to get) <em>We're desperate for</em> this enormous burst of emotions and feelings and it is well known that the <em>line</em> between being frightened out of your mind and feeling happy all of a sudden is <em>very blurry</em>. Adrenaline <em>rushing</em> through your bloodstream while you are riding a rollercoaster <em>with</em> steep drops, sharp curves and loops makes your heart beat faster and <em>you experience</em> the greatest pleasure of excitement and fear simultaneously.
The majority <em>of funfair</em> rides <em>such as</em> rollercoasters, thrill rides, the Top Spin and bungee jumping are rather frightening. They are designed to make your blood run cold and to leave you shaking like a leaf afterwards. <em>However,</em> not all rides at fairs are scary. There are some children’s attractions too<em> which</em> are <em>just slower</em> version of adult rides<em>, providing</em> fun <em>rather</em> than fear. These attractions include bouncy castles, mazes, carousels and other<em> ‘juvenile attractions’</em>.
As for me <em>personally</em>, the most frightening and exciting ride I’ve ever been on <em>was</em> a rollercoaster in Chelyabinsk. I adore the feeling of the high speed, but at the same time being thrown in different directions and dimensions makes me break out in a cold sweat<em> ("a cold sweat" is quite a negative-sounding description)</em>, yell at the top of my voice and feel extremely cheerful all at once.
Still there is one attraction which I’d <em>very much</em> like to visit, even though it’s not <em>particularly</em> connected with being scared but rather with experiencing spiritual pleasure. This is The London Eye. The main reason why I want to visit it is just to be able to comprehend all the beauty and the refinement of the city’s architecture and nature.
All in all, <em>a</em> feeling of intense fear sometimes can bring lots of joy and emotional discharge <em>which is</em> obviously beneficial for everyone, and that is why amusement parks are and will <em>continue to</em> be so popular.
All in all, <em>(instead of repeating "all in all" you could say "in summary" or "in conclusion")</em> my attitude <em>towards experiencing</em> intense fear is <em>very</em> positive, not only <em>does it make us</em> feel alive, <em>it</em> also brings huge amounts of positive emotions.

Rather than saying "brings joy" or "brings positive emotions" (which sounds a bit awkward) you could say:

- makes people feel happy/elated/joy

- gives a thrill

- is a source of positive emotions

- allows emotional release

How I spent my day today(Part 1)

I woke up at 6 a.m. today, <em>went over</em> to the window to draw <em>open</em> the blinds <em>and</em> drew them <em>open</em>, but it was still dark in the room. I went out to the balcony. <em>It</em> was rather cold outside, and from what I gathered I would have to dress warmly when I left my house. I returned to the room, where it was still dark, drew the blinds and put the lights on. I went to the bathroom and took a <em>quick shower</em>. After all this I went to the kitchen and turned on the TV, then <em>went over</em> to the fridge and took <em>some</em> mashed potatos <em>out</em>, put <em>them on</em> a plate, and put the plate into the microwave oven. While the potatos were <em>cooking</em> in the microwave, I took a couple of eggs out of the fridge, broke them and poured <em>them into</em> a pan so I could make myself an omelette. I also took a couple of sausages out of the fridge and threw them into a saucepan to be cooked. Meanwhile they were giving <em>today's</em> weather forecast on the TV, they were saying it would be cold and that it would rain. I'd heard <em>the</em> signal from the <em>microwave</em> before I was done with listening to the weather forecast, which meant my potatos <em>were already</em> cooked. I took the potatos out of the microwave, removed my omelette from the pan, and <em>took</em> the sausages out of the saucepan. While I was eating, they were <em>reading</em> the news on the TV. I had finished my breakfast before half an hour had passed. <em>(This is gramatically correct but I think "half an hour later I had finished my breakfast" or "it took me half an hour to finish my breakfast" sound better)</em> Then, having washed my hands, I put on clothes, took an umbrella with me and went out.
