Bananiot, if you’re looking for sporting purity; which you may have had to some extend in your innocent badminton days, you won’t find it in soccer with the amount of cash that’s being pumped into it!
And I’ll bet that had as much money been injected into badminton, your children would’ve been right up there earning it thanks to their dad’s advantageous position. With a high incentive they would’ve found the “passion” to play it overnight!
Without competition (rivals aiming to grab the medals and money from you) there is no sport as nobody is interested in whacking a ball all by themselves just for the love of it!
