Context: My legs and stomach feel kinda stiff but I think that 's a good thing . My tummy is full of salad , pizza and water :) And my feet hurt . I should not have done that in plastic flip flops ... Oh , and yesterday was great , as was to be expected . Got together with Mina , went shopping , ate incredible Indian food which totally hit the spot , then ate ice cream while watching several Yahtzee reviews , then came home and crashed .

Question: Why does your stomach and legs feel stiff after today ?
Options:
0. After I went shopping with Mina , I just felt stiff in general .
1. I devoured way too much Indian food and ice cream .
2. The pizza I ate probably gave me food poisoning
3. It 's probably because I had a long , but fun day .
Answer: 3
