How has the development of technology positively affected our wellness?

I'm not really sure if my answer is correct, but based on my logic and common sense, technology has helped because  technology developing would help create better and more advanced machines that could help us more/more effectively.

For example, back then, when technology was weak, people would place several fingers onto their wrist to hear their pulse, but that took time to find the 'correct' pulse. Now, with technology, you can easily slap on and secure some velcro and you can see your heartbeat/pulse on a monitor, which also tells you if you have a healthy heart or not. ( not that big of a difference, but it was all I could think of right now. I'm really tired. )
