i also swim 2 or 3 times weekly before at a club house. I swim at night usually after 7pm, But what scares me is that I tend to get sick often compared to before I started my routine. usually fever, flu or cough. Also I not sure why, but I feel yucky when I see somethings in the pool like any foreign stuff. Hence, next month Im trying to swim in another club house with another pool, hopefully I dont get sick often.

Also I think in Malaysia the weather is not nice to swim there are times i go change come out and its raining so I cant swim.

But its a good solo sport and can really can keep you healthy if you mix swimming with gym.
