Oh yeah? And I know people who do extreme sports with an extreme schedule whilst simultaneously breastfeeding. None of this invalidates the people who find any of the above to be too stressful.
I’ve been to congress, will probably attend more too. Some people find the schedule to suck, some don’t. I do not believe it will ever change. I think it is reasonable to find the schedule hectic. My pet theory that this one soft way of keeping the congress more about the chaos communications club rather than it becoming a tech/hacker conference with a strictly international audience. And that is fine.
