If I remember people and how I feel for them, then definitely this would be amazing.

before choosing this, i would make note of everyone that i know, even if it would take more than 15 minutes i would have a note to remind me. If i have long term memory loss as a result of this id keep adding to the note, which would become a notebook by then

Hm. Global earthquakes as the ground shifts and settles, and places with ground level near the 100m mark will probably get fissures spewing high-pressure liquefied whale from them. That's kind of nasty. But I wouldn't be surprised if most of the whale goo remains sequestered deep underground in the high-altitude regions and becomes a new sort of "fossil fuel" resource to tap into.
Ten years gives a lot of time to earthquake-proof our infrastructure, though it'll still really suck. Not as bad as most of the other world-affecting whale WYRs.
