All, I have been reading a lot about using HSA as a super charged investment vehicle from madfientist. I like the idea of it my only worry is them changing to laws around using that money as a traditional IRA at a certain age. I am also worried about not taking it out of the account when I incur and expense and saving my withdraws for later on. I am worried that they might change the laws and not allow the ability to use them for past expenses. Is anyone else worried about this? I know they could change the rules on any investment account, so should I try not to worry and max this out?
