Additional examples of quotes while wearing the age simulation suit for each theme (study 2)

Description of themes (agreement rates)	Example quotes
Theme 1: hearing (95% agreement)	“Everything was more tiring, duller. Even the movements themselves, even now when you talk, you hear yourself muffled and you perceive yourself completely differently.” (T003)
Theme 2: vision (96.7% agreement)	“To me, the worst feature of this suit is actually the insufficient sensory perception of eyes and ears.” (E4064)
Theme 3: strain and coordination (86.7% agreement)	“To me, the heavy legs were the worst. That you don’t have control over them, (incomp.) [that there] is a distinct gait disturbance.” (E4131)
Theme 4: negative affect (88.3% agreement)	“That does make you a little sad, I have to say, when the visual field is [tinted] yellow.” (T016) “I feel considerably older. That is very distressing.” (E4201)
Theme 5: future me (86.7% agreement)	“You hope that if you get really old that you don’t have these limitations that you experience through this additional equipment.” (T4081) “(…) but I can imagine that this is how it really is in old age. When you can’t do things like you used to, when your legs are heavy or perhaps you’re also in pain and you simply can’t perform the movements anymore.” (T4051)
Theme 6: empathy and insight (93.3% agreement)	“I’m relating all of this a lot to my 93 year old mother in-law who is exactly in this condition. Therefore, this was very frustrating to me. If this is the reality I feel even more sorry for her than I already do.” (E4225) “Then you do realize how the demands you place on somebody who might present themselves as very fit but actually experience these limitations (…) how it can burden them to carry three or two grocery bags home or to go to the train carrying a suitcase, or simple tasks like taking out the trash or going down some stairs.” (T4124)
Theme 7: other associations (86.7% agreement)	“I am a diver and before you go into the water, right this moment that’s what this feels like. You’re so heavy, you’re have all the lead and yes, that’s why I feel like finally going into the water so that it gets lighter.” (T004) “[It] definitely rather felt like sports training as soon as the headphones and (…) the goggles were off.” (T009) “When I think about some people perhaps carrying this weight as bodyweight then I think to myself: Good heavens! Well, I will aim to lose some more kilos myself. Because it really is straining for your body to carry so much weight.” (E4098) “Perhaps you walk like this when you’ve got a certain alcohol level in your blood. It was a little difficult to walk in a straight line” (E4098)

Qualitative data were assessed through one open question (i.e., “What was it like for you to wear this suit?”). Codes were generated by two independent reviewers (LIS and LCS)
