The mission of each sperm is never certain, because from birth it is full of uncertainty, which means that every sperm is full of expectations for the future. To stand out from the tens of millions of siblings, they need to have a strong physique and a unique personal charm.
From the moment they launched, they knew there was no going back, and the only thing to do was to keep going. Where the road lies, they don't need any doubts, just rush forward. Of course, the road ahead is bumpy and full of thorns. The first thing you encounter is the acidic environment of the vagina, which may not be the taste of any tongue, but an acid with a PH of between 3.8 and 4.2.
Along with this came a large amount of intracervical mucus and white blood cells, which, like guardians, resisted any invasion that did not belong to the land. A large number of sperm were defeated. There are only a few sperm, which we can call the lucky or the chosen ones. They continue to move forward, and finally come to face the huge egg.
In front of the eggs, they are like children who have made a mistake, shy and wild. Because the egg can only leave the position of one sperm in the heart, in order to win the egg at ease, they desperately rush forward.
This is very much like our life, when you feel that the future is a little slim, there is no need to move forward, there is no need to complain about the world, you just need to stick to the road under your feet, take every step, you are your own lucky person.
