Would this type of atmosphere be suitable for human life?

I've been trying to create a Earth-like planet but I'm not sure if my planet's atmosphere is breathable. (It's mostly the amount of helium I'm worried about).

I've tried to make it Earth-like while making it alien with respect to Earth's atmosphere. Here are the atmosphere's numbers: atmospheric pressure: 1.22 atmospheres; atmosphere composition: 66% nitrogen, 19.42% oxygen, 14.21% helium, 1.25% xenon, and 0.12% other gases.
