Dude.
The last time someone threw 400 innings was 1908. In 1908 the slider, the splitter, and the cutter hadn't been invented yet. The spitter was still legal in 1908. I also damned sure can tell you that the average speed being thrown then wasn't in the 90s at all.
Players also destroyed their arms and were never heard from again in 1908.
We also still primarily moved by horse and buggy, primarily communicated by letters, and were without phones, television, and the internet.
If you'd like to live like it is 1908, feel free to do it. I am fine with 2019.
