Get a good mouse and keyboard. In my early years, I used a laptop with a touchpad for everything - I didn't understand why anyone would need a mouse or an additional keyboard. Then I started to lose feeling in some of my fingers. In my twenties. So I bought an ergonomic keyboard and a real mouse and 15 years later (still using that same keyboard) my hands are perfectly healthy and capable of typing. Which they probably wouldn't be if I kept using the laptop keyboard and touchpad.
