Constrained by fear psychosis

When one person asked a middle-aged, plump man at the newly opened blood test centre whether he would test his blood group by sucking blood with a small pin-piercing method. 

He rejected his gentle request quickly. His plea was probably emphatic: we perform only through sucking blood by big sized needle. One person standing there told him that easy method tests are done at various other centres.

We do tests using the long needle piercing method. For the individual who had never had even  had an injection, it was certainly a painful test. 

He afterwards revealed that he had more often avoided injection; so how could he bear a long needle in his vein.

As the man was quite dreadful of the needle-piercing method into his vein, he proposed a method of lesser pain. However, the blood sucker stressed that he did not perform that older method. 

However one man listening to this very serious conversation said that one shop runs such an easy test. It was quite soothing news for him at the time. He showed his utmost interest in a blood test to learn his blood group.

Strangely enough, blood test centres take out a fixed amount of blood without any mercy. But that man does not like to waste his blood. 

His immediate fear was that blood formation slows in old age. He was therefore constrained by this severe fear psychosis. He does not want to undergo painful tests.
