Kids of this generation are losing out!

Very true, Gumball.

But I find on the whole these days that yoyo can remain interesting to kids far longer than it used to.

Back in the day, you got your Coke yoyo, learned walk the dog, rock the baby and Eiffel tower and your were done. Then the fad wore off.

Nowadays there is so much more to learn to keep it interesting, so it is potentially less of a cyclic fad.
