Nurse may find it difficult to get veins properly for blood test, but mosquitoes never err.In the clinical lab when the nurse needs to draw blood for testing, I have seen them struggling with many patients to get the vein properly. They have to tie the band, slightly tap the area etc so that the vein comes clear popping up.
But I wonder how the mosquito gets exactly the vein it wants to draw blood from!. There may be some lesson for us to know. The doctors and nurses may be taught the same trick. Today, within a few seconds, a mosquito exactly located my veins and had its stomachfull of my blood. I knew only when it flew away and my vein had an extra pop up of a small swelling due to mosquito bite allergy.
True that man has to learn a lot from other creatures. With all our artificial intelligence, we are still not at par with the small earthly creatures. Shame humans!
