Surely you have better things to do with 100K+ than learn how to fly! Considering the risks; the high likelihood you won't be prime for hiring until late in the second half of this hiring boom and the money cannot be thought "well spent". Not to mention, flying is not like it looks by any means--it's not driving.
I'm hiring and sitting on a large resume pile of highly qualified pilots who all missed the last hiring boom (pre-9/11) and truly had unlamentable and miserable times--flying in Africa and Asia on contracts, RJ furloughs, family separations, assorted family miseries--it goes on.
Lastly, seniority is The Game and starting at your age puts waaaay down the list.
