possible reasons include.. The needle is too close to a valve, the needle might have slipped out of the vein, or the tube may have expired.
There are several potential causes for blood flow into the evacuated tube to stop during venipuncture: the needle could have slipped out of the vein, the vein may have collapsed, the tourniquet might have been released too early, or the needle may be obstructed.
There could be several reasons why blood flow into the evacuated tube during a venipuncture might stop. The first possibility is that the needle might have slipped out of the vein, in which case repositioning it should solve the problem. Secondly, the vein may have collapsed, which often occurs in elderly individuals or those with very small or fragile veins. In such cases, a smaller needle may be needed. Lastly, the tourniquet might have been released too early, which can prevent enough blood from being collected. If not any of these, it might be a case of an obstructed or 'blocked' needle.

Three ways to protect oneself from the sun is;
1. Wearing sunscreen protection
2. Wearing sunglasses, long sleeves, and a hat
3. Getting outdoors before 10 am and after 4 pm when the sun rays are least strong
