Are we getting stronger or weaker?

With all the things that humans have now, compared to what we had 1000 years ago, are we becomming weaker?
Survival of the fittest doesnt seem to apply anymore, because people who are weak/stupid still recieve healthcare and continue to live instead of dieing off. So as a result do you think that humans continue to get weaker and weaker because of the mer fact that the weak are reproducing?
I think we are weaker and stronger
In terms of physique, I think that we are getting weaker or I would say lazier. If you look at our ancestors, they had to hunt to survive by killing animals much larger then themselves. Today, however, we no longer have anything to strive for we are not fighting to survive and feed ourselves. But there are two sides to every coin. Though we grow weaker in terms of strength and speed, we grow stronger in our intelligence. As we evolve we are growing smarter and wiser, learning from our mistakes. We continue to learn how the human body works and the more we learn the stronger we can all become. We learn what is good for us and what is bad and if your care about your body and health then you can become a very strong person both physically and intellectually. 


So in ways we are weaker but we have also never been stronger.
