If they are so "easily approachable," feel free to solve them any time. I think you'll find that solving problems in living systems (let alone in the clinic) is much more challenging than it might appear from a CS/physics perspective (https://www.quora.com/What-is-the-Andy-Grove-fallacy?share=1).
I'm not saying it's not worth trying (it's certainly a more worthwhile endeavor than getting people to click on more ads), but that it's important to be realistic (for example, that all disease is unlikely to be cured by 2100).
