If suppose luckily me and Aishu meet up in person, can we play the game of tag or have running to race to remember our childhood or are we too old?

As you all know Aishu was my close childhood friend when we were in elementary school in 2008-2011. We used to play a lot together and be full excited when it used to rain. Now she is 21 and I turned 22 just almost 4 weeks ago and she is 5-6 months younger than me. We chat on Instagram and still remembers me but we rarely chat as she doesn't reply to my message for a week or so. But if suppose we plan to meet each other one day soon, can we still play around playing the game of tag or have running race and do lots of silly talks like we did as kids or are we both too old to do all that now as 21 and 22 year olds?
