Does Blackjack Teach Tight-Agressive Poker?

Before I caught the poker bug, I used to mainly play Blackjack in Vegas. Sometimes even going on all night Bobby Bracelet type benders. Since I started playing poker, I don't play much Blackjack anymore. It's just not that appealing, and seems to "brainless" to play anymore compared to poker. I was in Vegas over the weekend, and had some down time at a locals casino and sat down for some $2 blackjack. It finally dawned on me that correct blackjack play is "tight-aggressive". Anybody who has played blackjack for any amount of time and is not just spewing chips plays it tight-aggressive. The tight part is learning how to stay on non-winning hands like 12, 13, 14, 15 when required. The loose gambler hits those types of hands too often in the wrong situation and looses as a result. You have to play tight and be willing to stand on those types of hands to have a chance. So what's aggressive about blackjack? The tight-aggressive poker player tends to hold on to his/her chips, until they have the best of it, and then they have no problem firing at the pot. In blackjack you do the same thing to some extent. When you have a pair or an 11, or 10 the rules allow you to double your bet. If it looks like you have the best of it, then the tight aggressive blackjack player get aggressive and gets the chips in while good. Ultimately, I ended up being a tight-aggressive style poker player, and I am starting to wonder if all of that blackjack training set me up to play that way. Any thoughts?
