ok here is a reason why walking and exercise actually doesnt increase iq

[MVP]

look. walking heats up your body, which decreases iq as ppl from africa are actually low iq i was walking every day but didnt notice any iq benefits. there are lots of studies and stuff claiming it increases your iq but everyone is different, i my case, i rather feel worse after walking say 30 minutes every day, i feel like my body has been heaten up, and i dont like it, i prefer to be cold.
