You keep it up whilst you can!
One day, it can all end without you wanting it or being ready for it.

This is me 18 months ago on my 50th birthday.
I've never eaten healthily, never been to a gym and play no sports.
I smoke and I used to like my amphetamines.
I ran 5 businesses and hardly slept.

I thought I was staying pretty preserved for my age, considering the above poor lifestyle.
Then BANG, I had a heart attack and developed heart failure and can barely work. I've gained 70lbs!!

I deserve no sympathy as anyone who knows me tells me, I've been heading towards it for decades!

My point is: Do what you can, whilst you can, whatever that is, as long as you enjoy it.

I'm just going to have to buy myself one of these hoody tops!
