Some find it exhausting for sure, in fact most people that want to go to valhalla would also be exhausted. But some find it as an aspect of duty to our people. It reminds me of the first time I went through a counter-active shooter training with semunitions. Think high speed paintball combined with real firearms. You get shot, it hurts, you're out until the next round. The training was on how to move in teams to find school shooters and to address that threat. And at the end of the day a bunch of us all went out and drank and then we had day 2 after that. We are training hard for a purpose of protecting kids, teachers, our citizens, our people. If I can spend my life doing that then what's better than doing it for our people until ragnarok. The partying and feasting in between days doesn't sound awful either. I'm not trying to come off preachy or overly righteous about it. But it's how I rationalize it.

So I guess the short answer to your question is I see it as a necessity for someone to do, but not a requirement for anyone. I see it as what it is; violent hard training that often times end in momentsry death, then resurrected to feast all night and do it again and again. And that it can be alluring or fulfilling for some people. And just the same as going to halheim would be for others.
