Yup...
My time in Muay Thai changed my outlook on my body/head protection priorities. One can condition the torso to take tremendous blows by just being in shape, by learning to fade or turn slightly, by accepting the impact on slab muscle, with kiai and so forth... most of which options really aren't as available for defending your dome. Best thing about defending kicks to the head is that it's a rapidly moving target..... But, best imo to keep the hands way up there and keep them feet off my head. Feel free to kick me in the chest, abs, hips legs. That, I can deal with. But mess up once with a good head kick and you are most likely done for a while. And no... this is not a call out to you fearsome kickers who can put your foot through a '76 Monte Carlo... I won't be there just waiting, that's not what I'm saying.
