You just hit your next birthday. Not only do you age up this next birthday, but you also level up. As you level up if you could pick one skill/area that you would put your EXP points into (think like RPG games) what section would that be?
I would pick anything that buffs my physique/physical body as the older we get, the less it likes to work so anything I could use for mitigating that would help. What about you, what would you pour your EXP into?
