Myself and my siblings were all swimmers (DB's were Commonwealth Swimmers)
We grew up in Singapore until I was 15, and muy Father ran the local swimming club. The Australian National coach at that time was in the Australian Army and lived next door.
We swam everyday, twice a day, not because we had to but because we wanted to.
Although I really enjoyed it, by the time we came home I had enough, the nearest pool was 45 minutes away, so after a year I gave up.
My two younger brothers carried on till they went to Uni, at which point they had other interests.
Although I dont ever regret it, my self and next brother down have problems with joints and muscles ( I have Lupus) when I went to see the specialist, he said he had never seen such over developed shoulder muscles (which are now causing me to have a 'hump')
I swam 400m Fly for 6 years, it can do that to you.
