Another reason could be some external factors like being pushed into the river accidentally or getting caught in something underwater while swimming, which restricts his movement and leads to drowning.
He might not be a good swimmer and overestimated his ability. Maybe he entered the deep part of the river without realizing the danger.
Perhaps there were strong currents in the river. Even experienced swimmers can get into trouble when faced with unexpected and powerful currents that can sweep them away.
One possible cause could be the strong currents in the Rio Grande. They can easily sweep away anyone who is not a strong swimmer.
One can immediately throw a floating object like a lifebuoy or a log towards the man. This gives him something to hold onto and stay afloat.
One possible cause could be exposure to the elements. Homeless people often lack proper shelter, and in harsh weather like extreme cold or heat, they are at high risk of succumbing to the conditions. Another cause might be lack of access to medical care. Since they don't have a stable living situation, it's difficult for them to get regular check - ups or treatment for pre - existing health problems.
It could be drowning, as the story is set on a river. Maybe the character was boating and something went wrong.
One possible cause could be a high - cholesterol diet. If a man eats a lot of fatty and fried foods over time, it can lead to plaque buildup in the arteries, which may trigger a heart attack.
Poor supervision and lack of safety awareness are common causes. To prevent it, parents should always keep an eye on kids near water and teach them water safety rules.
One possible moral is that we should not be indifferent to the plight of others. In the drowning man story, if people ignore him, it shows the callousness of inaction. So, it teaches us to be empathetic and act when we see someone in trouble. It also might imply that we should not be too self - centered. If we are only concerned about our own affairs and turn a blind eye to the drowning man, we are lacking basic humanity. Overall, the story encourages us to be more altruistic.
One possible theme is the fragility of life. Drowning is a life - threatening situation, and it can highlight how easily life can be lost.
It could be that he had a past experience related to a dog. For example, he might have been saved by a dog when he was a child or had a special encounter with a dog that made him feel a connection. This connection then drove him to save the stray dog from drowning.
The moral is not to rely on false hopes. The drowning man grabbing at the straw thinks it will save him, but it's too weak. It shows we should look for real solutions in difficult situations instead of depending on things that seem helpful but actually aren't.
