i do not know exactly what he is refering to. he could be talking about his specific art and that art might have made a lot of changes over the last few years.. we dont know.
you say you have been studying since the "old" days. that is kind of arbitrary. what is the old days exactly? where you studying in the 1890's ? the 1950's? 60's , 70's ???
at least with karate, i can say that training has changed a lot over the years. i do think we are overall better now then ever before, but there is something to be said about the "instant gratification" generation today.
i also do think the prior generations were tougher. not better but more acclimated to hardship. there can be no doubt that a farm boy working 365 days a year 14 hours a day doing farm work is a bit more hardy then someone sitting behind a desk for 10 hours a day looking at a computer screen typing his opinion on an MT web sight..
