I took my 16 yo kid skiing and he met up with a couple of his friends. I expected to just ride up the chair with them and then I'd go my separate way till lunch time but they were cool with me skiing with them. We did some terrain park stuff and Lucas' friends were fairly amazed that I would go off the jumps with them. Nothing special, just straight ahead air, but you'd have thought it was Johnny Moseley stuff.
Rec league soccer: I play with some office mates in a coed 7v7 league. I have millenial office/teammates saying "I can't believe how fast you are!" Of course, I feel like I've lost several steps.
