It is important to realise that an acre can be measured in any shape - from rectangles to circles or even hexagons - so long as the total area of land is 43,560 square feet. The most common shape for an acre is 1 furlong by 1 chain, or 660 feet by 66 feet. If you're struggling to get your head around just how big that area actually is, try visualising 60% of a soccer pitch, 75% of an American football field or 16 tennis courts in a 4x4 formation. If that doesn't help, consider a car park containing 150 cars parked in a square.
Introduction. Aspirin is an antiplatelet medicine, which means it reduces the risk of clots forming in your blood. This reduces your risk of having a stroke or heart attack. Normally, when there is a cut or break in a small blood vessel, a blood clot forms to plug the hole until the blood vessel heals.
Nearly 12% of people taking aspirin to avoid first heart attack or stroke should not do so, researchers say. Aspirin is a popular drug for people whoâve never had a heart attack or stroke and would like to keep it that way.spirin -- also known as acetylsalicylic acid -- averts heart attacks and strokes by preventing the formation of blood clots. Clots are made up of blood cells called platelets, which stick together with the help of an enzyme known as cyclo-oxygenase, or COX. But aspirin prevents COX from doing its job.
