Eek, there’s a challenging topic!
Actually on reflection it probably isn’t. Going travelling on my own (joining small group tours) whilst I still kind of physically able to was a very good decision on my part. Technically choosing to go to cambodia was last year’s decision but the spontaneous decision to go to Ireland was back in January. In hindsight, if my trip had been much later in the year (I went in July I think), I wouldn’t have physically made it through.
